Okay, I am back in. I wasn't too worried because I did a Google search on that error message and it came up a few times so I could read up on it here on the boards, seems to be not entirely uncommon. They also said it took more like 40 minutes instead of 20. Turns out it took about 30 minutes, for me.
My reservations as far as I had made and confirmed them (one at a time) were still there. I think I shot the system by becoming too bold and trying to reserve two items at once, without submitting after the first.
But anyway - it's a success story for the most part:
- I have secured Palo dinner (not for the night of my 1st choice but 3rd choice, apparently Pirate Night. Saves me from having to find a pirate costume

).
- Didn't get Palo brunch, but I wasn't the only one and I had already heard they were all gone somewhere before.
- Got Tulum!
- Got the Seven Mile Beach Break (the one in the morning).
- Got the Exotic Rasul.
- Got the Stingray Adventure on
Castaway Cay.
I guess that's it ... although I am so happy at the moment I might just go wild and find myself a nice little spa treatment just for myself ... Let's go shopping
