The 10 cheapest US destinations to visit this summer

Summer is one of the most popular times of year to travel, but you can still find great deals on trips if you know where to look.

TripAdvisor just released the results of its annual TripIndex Cities study, which compares the cost of a three-night trip for two people across 39 popular tourist cities around the world.

To find the top 10 cheapest US destinations, TripAdvisor compared the cost of a three-night stay in a four-star hotel, a visit to three attractions each day, the cost of lunch and dinner each day, and the cost of two Uber or taxi rides of two miles each way per day.

The prices for lunch (a meal and soft drink) and dinner (a starter, a main meal, and a bottle of wine to share) were collected from menus on restaurant websites. Transportation costs were based on prices from Uber and from local standard taxi rates. Attraction rates are based on the price of entry for the top five activities in each city, while hotel rates covered the average cost of a one night's stay in 4-star and 4.5-star hotels from June 2 through September 30 2016.
