I am traveling around 100 days due to my consulting business - mostly in Europe and in bigger cities. When I stay 1 week or so, I prefer to stay in an apartment instead of a hotel. Even if the check in and out may be little more tricky than in a conventional hotel, the living reminds little more the ordinary life.
I like to go swimming after my working hours - if only there is a decent pool around. If not, gym works as well. And when possible, I try to add 1-2 skiing days to my trips.
