Kat- FYI I got an email from my old team saying it sold out in 11 days last year, after selling out in 30 days the year before. Good thing you have the alarm! I would expect it to sell out in single digit days if not opening day. 
I feel the ride is worth it if you can commit to fund raising and the travel. It was $50 last time I did it (I think) and I thought that was a fair price. You get a t-shirt and water bottle, plus a good lunch both days (not common in TX), dinner Saturday and breakfast Sunday if you are at the campgrounds. The campgrounds are fun and if you are on a team you will have a big covered tent which everyone bunks in. It was weird for me but really fun, I highly recommend the campground experience but then again we like camping anyway.
