My wife and I will be at CSA May,22-29 2011(First Timers)! Her graduation will be on the 21st(doctorate degree) So this will be much needed for her. Its a surprise also. When you book is it best to call our do it online.... For first timers. Also the payment part, do we pay as much as we want untill the 45days out,our do you have to pay so much a month?
