im leaving this sunday for a western carib cruise. its my girlfriend and i's first cruise and we could use any tips or info you would be willing to give us. its a seven day cruise and we are looking to have as much fun for as cheap as possible. is there any way in the world we can get alcohol on board besides paying for drinks at the bars/restaurants? is it better to do the excursions offered independently onshore rather than through the boat? once again, any info would be GREATLY appreciated. please let me know- thanks alot!
