I go through the registration, enter all my info (it does save it and I can close and re-login later), and add one additional to my party to pay for. I get to the Book Hotel section (which I can't do since they all sold out and now I have to go get a hotel in a neighboring city lol urg), but I can't find any way to get to the summary section and check out. It gives a warning saying "Please Check Out and provide a credit card number to complete registration and confirm your hotel reservation." The only two buttons are Edit Your Registration (which takes me back steps) and Book Hotel Reservation. How can I proceed?
