Reimagining Key Onboard Experiences
From Overload to Enjoyment






What is Carnival Hub?
Carnival HUB is Carnival’s official mobile app that helps guests explore activities, book services, manage plans, and navigate their onboard experience.
The Problem
Carnival has many potential customers that now bypass traveling by cruise ships as vacationers have changed how they plan trips. In response to this, the cruise line industry has tried to make the cruise ship itself a highlight destination with events and attractions to entice travelers.
However, due to the sheer volume of activities and events provided, it is difficult for guests to know what is available and what would most interest them.
This project aimed to reimagine the Carnival HUB app through research-driven and experimental design exploration.
Our goal was to deliver validated design recommendations and a future-state prototype that could inspire Carnival’s digital innovation roadmap.
The Process
PRosona
Understanding the core users
We first considered segmenting guests by travel group types — families, couples, friends — but quickly realized these labels didn’t reflect how people actually make decisions onboard.
Through user reasearch, we found clearer behavioral patterns that better guided design:
The Planner needs clarity and structure
The Explorer seeks guidance without restriction
The Relaxer values simplicity and trust
These personas aligned with Carnival’s internal insights and became a more actionable foundation for shaping the experience.
Comparative Analysis
To understand how the Carnival HUB app compares to other travel and entertainment experiences, we also reviewed 4 competitor apps across cruise lines, resorts, and theme parks.
What We Learned
Carnival has strong onboard activities and experiences, but the current HUB app focuses too much on showing information.
Problem statement
Despite offering a wide range of onboard information, the Carnival HUB app does not effectively guide guests toward confident and meaningful choices. The experience feels informational rather than inspirational,it only helping users find activities, but not helping them feel fun or in control while doing so.
How Might We
Key painpoint
Overwhelming Choices
The same app experience serves everyone, making it hard to find relevant activities.
Lack of personalization
Gusets struggle to decide what to do because there are too many options and limited time.
Disjointed Navigation
Guests must jump between sections to find what they need, losing track of context.
Emotional Disconnect
The app focuses on logistics, not the excitement and fun that define Carnival’s brand.
Opportunity areas
Smart Discovery
Personalize recommendations based on guest type, location, and time context.
Journey Clarity
Simplify information architecture and create a guided, goal-based navigation flow.
Shared Experience
Enable coordination and shared planning among friends and families.
Emotional Engagement
Infuse visuals, tone, and interaction moments with Carnival’s joyful brand energy.
Ideation
Design Value Framework
Ideation
Generating Ideas Without Limits
To generate and refine ideas around these questions, we facilitated a structured yet highly creative ideation workshop focused on divergent thinking — aiming for quantity over perfection. Our goal was to explore freely, not evaluate, allowing every idea, no matter how bold, to surface and spark new connections.
The session resulted in dozens of quick sketches, written ideas, and sticky notes — spanning interaction concepts, content strategies, service moments, and future-forward possibilities.
In addition to human brainstorming, we also leveraged AI to generate alternative concepts and edge-case ideas. These AI-generated prompts were mixed into our idea review, helping us challenge assumptions, broaden our thinking, and push beyond our initial patterns.
Ideation
Future-State Strategy
We grouped and compared all ideas, then discussed which ones best aligned with guest needs and Carnival’s brand vision. From this process, we distilled two strategic directions to develop and test further.
Key criteria:
Desirability – Do users actually want it?
Feasibility – Can it be realistically built within technical constraints?
Viability – Does it create long-term value for both guests and the business?
Dual-Strategy Designed
to Serve Every Guest
We built the solution around two things that work together for every guest. The Treasure Hunt brings the fun—more energy, exploration, and little moments of delight. The core UX upgrades keep everything clear, easy, and scalable. Together, it’s a balanced experience: it guides you without feeling bossy, and it feels playful without getting overwhelming.
Information Architecture
Structuring the Experience
We restructured the IA and tested several models to align with both user mental models and Carnival’s brand flow — Discover → Plan → Experience → Reward.
A key change was setting Treasure Hunt as its own module, creating a clear, end-to-end experience that connects play, reward, and brand loyalty.
This structure reduces cognitive load and opens room for future growth — from leaderboards to social and seasonal events.

Set Context in Seconds
Quickly explains what the game is, how it works, and what you’ll get—so first-time guests feel confident, start playing immediately, and keep coming back.




Personalized Storylines
Package routine actions into Game missions
Tailoring missions, routes, messaging, and rewards (e.g., families, couples, first-time cruisers, foodies)—so the game feels relevant, reduces choice overload, and drives participation and onboard spend.

Clarity Before Commitment
Game Detail Screen
Combines story, filters, rewards, and time limits so guests instantly know what to do, where to go, and whether it’s worth joining.



Before & after
As an academic–industry collaboration, the project moved beyond deliverables to demonstrate measurable impact — validating how research-driven design can shape future digital experiences. From delivery to impact, this project turned research-driven design recommendations into meaningful improvements in clarity, engagement, and brand experience.

Design System
The challenge was balancing joyful brand energy with a clear UI. Too much fun distracts. Too much clarity feels bland.
I tested directions with Experience Boards. I used fluid gradients and rounded motion for energy, while keeping key actions high-contrast and in fixed spots for fast, confident use.
Components

Reflection
In complex, real-world contexts, UX isn’t about adding more features—it’s about reducing mental load so users can quickly understand where they are, what they can do, and what to do next. Small friction gets amplified, so the best UX decision is to keep the experience predictable: consistent key actions, clear hierarchy, and task-based guidance. Delight should support the flow, not compete with it.
Reduce confusion first. Delight comes next.
Lesson Learned
Design Within Constraints
Even without on-site testing, scenario-based simulations can reveal real user behaviors.
Design as a Strategic Lever
Aligning with KPIs and measurable outcomes connects design to business impact.
Balance Playfulness and Clarity
Emotion and usability can work together. Clear hierarchy and thoughtful motion make both possible.
