I travel a bit, too, and I ended up jumping 7 different DZs in 6 states within my first 20 jumps in an attempt to stay current. No one ever held it against me, and I think benefited from being exposed to a lot of different instructors, aircraft, landing areas, equipment, etc. Of course, there are also advantages to jumping a familiar DZ with instructors who know you. I'm sure there are plenty of instructors who could make a great case for doing all your student jumps at the same place. It's a choice, and I definitely don't think there's anything wrong with jumping as many DZs as you have the opportunity to. After my two short years in the sport, I find that most of the skydivers I meet are pretty well traveled, and I often meet the same people at different DZs.
