I'm in a similar situation where I only got accepted to a private school while waitlisted at public schools. When I weighed my options (paying for private vs. waiting another year and hoping to get into a public) I decided that nothing is more important than becoming an OT and I'll do what ever it takes.
Considering the incredible growth in number of applicants that most of the schools saw this year, I can only imagine that it is going to get more competitive. I'm convinced that when the economy took a dump in 2008-2009, a LOT of people started to reevaluate their lives/careers and discovered this wonderful field. That coupled with the positive #'s in the pay and job market, I have a feeling that it is only going to get more competitive.
I've seen too many people on this message board mention how they were waitlisted at particular schools last year and then were surprised when they were straight up rejected this year. I can't imagine what that must feel like and refuse to take the chance of something like that happening to me.
Bottom line, I am honored to have been accepted into a program and am ready to get these next 2 1/2 years knocked out so I can start working as an OT!!
