So where will your wallet feel the most empty? To figure this out, we took our spending data and looked at millions of transactions for 40 popular vacation towns in the U.S. in the following categories: shopping, food, hotels, movie theaters, public golf courses, public transportation, taxis and limos, tourist attractions and exhibits, and travel agencies. We averaged the spending for out-of-towners visiting each of the vacation towns, and then looked at which towns had visitors spending significantly above the norm.
