I think it is too much travel for even a college team. They do have lives and are given breaks occasionally.
I have to wonder at the logic of the coach/manager.
I'm assuming the reason for travel is to play at either national championships (ASA/PGF) and/or huge showcases. There would be top-notch competition at these games. How does the coach/manager think these girls will maintain a competitive edge sleeping crammed in a box for 2 weeks on end, vs. girls who have slept in a hotel.
The point of playing championships and showcases is to play well, not just to show up.
