We've said it before, and we'll say it again: Some "tourist" attractions are 100 percent worth visiting. The ticket-booking app Whym gets us. The app offers travelers last-minute deals on desirable activities like guided tours of the Colosseum in Rome, U.S. city passes, Parisian wine tastings, Nevada desert sunset horseback rides, and admission to all kinds of museums at deep discounts—up to 60 percent off. All you need is a smartphone: The app is available for both Android and iOS (free, itunes.com, play.google.com).
Deals are currently available in London, Barcelona, Paris, San Francisco, Rome, Los Angeles, San Diego, and Las Vegas, with New York City coming soon.
Each city's curated list is handpicked to accommodate a variety of travel interests. A few discounts that we liked are a London Landmarks Bike Tour (think Big Ben, Parliament...) for about $28 instead of $36, a Grand Canyon National Park VIP Tour for $163 instead of $199, and a Go San Francisco Card (which gets you into 30 top attractions, plus discounts on dining and shopping) for $49 instead of $60.
Choose a city, scroll through options in the area, select how many tickets you need and the time, and then pay for your tickets, which are stored in My Purchases and/or emailed to you.
Pretty simple—and very smart.
