I'm not sure that the offices are closed on the weekends. In fact, I'm pretty sure that the sales office is open on the weekends. It's member services that is closed on the weekends, but you wouldn't need them today anyway. You can call the sales office and have them send you the dream book (it can be delivered by FedEx). Once you get that (or before if you're really ready), you can tell your guide that you are ready and how many points you want. You give them a credit card number for your deposit and you will be entered into the system. You can call member services the next day to make your reservations using your points (or maybe even that afternoon). As for your other reservation, I was told that as long as we were more than 45 days out, we could cancel with no penalty. Hope this helps.
