As soon as you can, make reservations for any of the shows or acts you want to see.
We were not aware of this, and when we went to make reservations on the first day, everything was booked. I'm sure the are several people that made multiple reservations, either to see the show's multiple times, or in case they couldn't make a time, they had a backup. This is why they have stand by lines, but that's not always a guarantee.
Reservations also go for the boat tenders at Cabo, laser tag and go carts.
The cabin was sufficient.
Our steward was very nice.
