I used to feel the same way. So I tried a short one!!! I have pictures of me almost in tears on my last day!!!!!! Its so awesome. You meet so many people and believe me you meet cuties on the boat too!!! My waiter was from dag I forget which Carib island and he was fine!!!!! But they can get in trouble for associating with the guests too. You barely know your on a boat but I would say try a short one first.
