A quick thought to add to Adventure Girl's post. I use my hybrid rather than my road bike on the trainer. As a matter of fact, I just put it on in anticipation of less light to ride in after school and those cold winter winds. That allows me to ride my rode bike when the opportunity and weather allow but the trainer is always ready. One the time issue, I bought a rim trainer (rubber wheels for resistance roll on the rim rather than the tire) so that I wouldn't have tire wear problems. I got mine off of e-bay for a pretty good price - which I can't exactly remember now - old age sucks!! I have also ridden the exercise bike at school and have hated it. 1) it doesn't fit, the saddle is tooooooo wide and 2) I keep forgetting that it is a weighted wheel that won't free wheel - ouch on the knees. Just my 2 cents worth.
