I won't say I haven't considered the drink package, and I won't say I won't buy it in the future. I can easily drink 4-5 vitamin water zeros a day(I'm an addict) which I'm sure cost 3-4$ on a ship, but I can just as easily drink plain water. I love good coffee, and non-fat lattes, but I can get by with the bad coffee. I love milkshakes, but don't like the calories. I could buy one have a few sips and slip it to my kid. As far as alcohol goes I usually drink a martini before dinner which tend to be expensive. At dinner 1-2 glasses of wine so 3 drinks max. I could find a way to get my money out of it without being hungover for 7 days straight.
If I ever buy it it would be as a fun splurge. I wouldn't buy it with the goal set of getting my money's worth out of it. I could try different martinis without worrying about the cost. I tossed out two 14.00 drinks on the Dream last month that I didn't like. It would be fun to try some more expensive wines and liquors. I could have some fun with it. It would be similar to the time we bought the deluxe dining plan at Disney world. I didn't buy it with the intent of eating myself to death. Cost wise it was more then if I would have paid out of pocket, but it sure was FUN. We ate at every signature restaurant, ordered the most expensive things on the menu, tried all the fancy desserts, ordered weird appetizers that we wouldn't normally spend money on all without giving a second thought to cost. I could find value in the drink package, but maybe not for the same reason other people find value in it. As we all know from hanging out on this board value is very subjective.
