EconomPic first highlighted the "staycation" phenomenon last year (i.e. choosing to vacation at home). Since that time, tourism has rebounded within the U.S. albeit to a much lower level than pre-crisis.
Note these figures were only recently released through Q1. I'm interested in what happens this summer... will travelers bounce back following a hiatus in vacation travels over the past few years, will recent market volatility / continued employment issues keep travelers at bay, and/or will a strong dollar prevent foreigners from visiting / push high-end travelers (i.e. those that have bounced back with regards to consumption) to travel abroad instead of keeping the $$ in the U.S.
