IF all is running on schedule (no storm delays, etc.) the port opens to incoming traffic at 10, the counters open for check in at 10:30. The big doors open at about 11:45. We usually try to arrive at the terminal about 11 - 11:30. This puts us in the first 150 or so people boarding, and I've never had any trouble getting any ressie I wanted using this schedule. I will put in the disclaimer that ALL my cruises are on the Magic (although 2 of them were from when the Magic did 4 day cruises). Palo and spa ressies do fill more quickly onthe 4 day as there are only 1/2 as many ressies for the same number of cabins.....
