Design a mobile app for Disney theme parks.

This question seeks to evaluate your ability to conceive a product that meets the needs of the users and aligns with the objectives of the business, in this case, the Disney theme parks. You need to understand elements of mobile app design, user experience (UX), and have some knowledge of the Disney brand and their theme parks.

Firstly, consider the likely users of the app (Disney theme park visitors of all ages and their families) and what features would enhance their experience. It's also critical to know the business objectives: driving ticket sales, increasing visitor engagement, promoting attractions and events etc.

Secondly, integrate all these insights to design a hypothetical mobile app with features and functionalities that meet both user needs and business objectives. Remember, the attention to details here is important as it shows your ability to think through a product design problem.

A Disney theme park app should be visually appealing and easy-to-use, fully embodying the Disney brand's colourful and fun attributes. The core feature of the app will be the real-time map of the park, providing users with directions, distance, and estimated travel time to various attractions, dining options, restrooms etc. This will be complemented by real-time wait times for rides and shows.

Additionally, we could provide an option to buy and store tickets digitally within the app. The app should also include a scheduling feature where users can plan their day in advance, schedule shows or make dining reservations, and get alerts/reminders.

For enhancing the user experience, we can include an augmented reality (AR) feature that brings Disney characters to life for interactive experiences. Finally, the app should have integrated social media functions for visitors to share their experiences directly from the app.

To design a mobile app for Disney theme parks, it's primary to center the design on enhancing the overall experience of park-goers. The key features should include digital tickets, personalized journey maps, real-time information on attractions, a scheduling system and a gamified rewards system.

Visitors should be able to purchase, store and scan their park and ride tickets from the app itself, reducing the need for physical tickets. Personalized interactive maps can guide users around the park, highlight attractions, suggest routes based on preferences and provide real-time updates on shows and wait times for rides.

The scheduling system will help users plan their day, book fast passes and make restaurant reservations beforehand. And a rewards system could encourage users to explore more of the park, participate in park events, and it can be leveraged to offer personalized deals.

Lastly, incorporating a merchandise store in the app can provide an opportunity for Disney to boost its merchandise sales, improve customer engagement, and enhance the overall Disney experience.
