Hmm. Good questions. For the most part food and photography are pretty high on my list. I'm not a big arts museum kind of person but I do love artifact/history museums.

My boss probably wants me to take short trips but I find those less fulfilling in terms of actually being a vacation - if I'm not gone long enough to not think about work for a few days there's not a lot of point. 1-2 weeks is probably ideal.
