Why do you think it would be a mistake? Other cruise lines do it and from what I can tell, it has had little affect on guest behavior. If the price is correct (55.00 a day for the entire cruise) I would think that it would rule out a lot of younger cruisers. According to what has been reported, if one person in the cabin orders the drink package, all people over the age of 21 in the cabin have to buy it as well. I would think that this would keep many away as well. I'm thinking that they put a high price on it not just to make money but to keep certain groups away from buying into it. I may or may not drink 55.00 worth a day, but it would give me a piece of mind just knowing that I dont have to keep track of it.
