The casino is usually closed when in port. Even the Bahamas - I remember as we gamble whenever casino is open. Definitely go and check out Atlantis. Personally I would see if I could upgrade at a small cost to a Junior Suite which is the next category up from Superior Oceanview. If the cost isn't very high it would give you more room and a balcony is soooo nice.
Superior Ocean View - avg. sq. feet is 157
Junior Suite - avg sq. feet is 255 + 60 for the balcony.
JMHO!
