Mobile App for Selling Things to Do Tours Activities Theme Parks Attractions

I am building a mobile app that sells same day (today only), last minute, discounted tickets for fun things to do while on vacation or in a destination. The .com name needs to be a global name and we will have cities/destinations within the mobile app. Things to do include tours, activities, guided trips, theme parks, attractions and shows. The cities/destinations are in places that people vacation like Orlando, FL, Las Vegas, New York City, etc.

Example: ThingsToDo.com Orlando.ThingsToDo.com (city/destination within the app) We would sell Disney, Universal Studios theme park tickets, Gatorland tickets, Arabian Nights show tickets. People buying the tickets will be vacationers traveling to the city/destination, plus locals who live in the destination.
