It sounds silly, but I really do. I toured ireland by bike with a friend of mine (so I wasn't alone) and there were a few times we split up and went off onto different paths, then would meet up later. I liked seeing things, meeting other people, and finding little used bookstores to sell of my previous book and buy another. Then I'd find a little cafe or restaurant and read a little.
I guess that's mostly just to say that you can really do whatever you enjoy normally for fun; sometimes it just feels better doing it in a different location, around a different culture. At first I thought "man, I wasted my money flying out here to read" but then I realized that I really liked it, and so, who cares? It was great.
I agree with the sibling post, also. I spent about a month in Thailand on a grand or so. We went all over the place. Chiang Mai was my favorite area, personally. Lots of culture, and lots to see all over, though.
