Would the list be similar for US citizens? As a Brit, I was slightly surprised not see Hawaii or Alaska featured, as those are the states which seem most attractive to me.
Probably similar, but definitely not the same. Not sure if that source has domestic trips in their database. Hawaii and Alaska are extremely far from Britain, and Alaska is cold, which is probably one of the very things Brits look to escape, as well as being visited very little in general, unfortunately.
