Page 1 of cruise ships

Hi all, i am at the moment considering working on a cruise ship thinking that it would be a good chance to travel whilst earning some money. Im looking to be doing bar work as im in the industry at the moment, and really just wondering if any of you guys have done anything like this before? If so let me know your good and bad stories and whether you think it be worth or not, also any recommended companies to go with. Cheers guys
