TripAdvisor is the world’s largest travel site, so we’re assuming you’ve either a) used it, b) heard of it, or c) you just don’t travel. But if you don’t travel, you wouldn’t be on our site right now reading this. So you’ve probably heard of TripAdvisor, and for good reason. This one-stop-shop allows you to read millions of reviews, compare prices, and book your accommodations and flights. You can even use it for restaurants—type in a city or a restaurant name, then see pictures, customer feedback, ratings, and a map. So whether you’re going to Costa Rica for a three-week-long holiday or just looking for somewhere new to go to lunch, TripAdvisor is your go-to source for planning your adventure.
