Hello Mike. I would suggest going in Greece. It's an awsome place( I was there this summer. Don't know if you can swim with the dolphins (I only swam with fish) but you can do a lot of other things. And if you want you can choose a mor elonely location like a 3 hotels complex so not a lot of people there to fuck your mind out
(this in case you want to relax too)... as far as I know it is still sunny in there
