Casinos in Nassau, Freeport Bahamas via cruise?

I will be taking a Carnival cruise (Carnival Fascination) in July. Anyone tried out the casinos in the Bahamas? Were they close to the ports? Limits and structure? Could not find any good info online. Also anyone have any idea about the casino on the boat? My last cruise was with Royal Caribbean. They only had 2 poker tables, one tourney and one limit table (2-4 I think).

Nevermind found some info on 2+2. Looks like its poker pro tables on the boat. 1/2 NL with pretty sick rake. No poker tables in the Bahamas running unless PCA or something.
