And even the 11th took 28 mins to sell out. So if you get on at 1pm cancun time (currently = us central time) you will easily get on your cruise. The day it opens up is always posted, usually 1 month before cruise date, sometimes a day later if there is a cruise that date and Steve is out on the water. So the end result is if you really, really want on the cruise you will get on it by planning and being sure you are available at the time it opens.
