From my conversations with
DCL the standard size carry on that you would use for a plane is acceptable for DCL.
The cooler thing is interesting to me as I can't get a real answer from DCL as I am not wanting a whole 6 pack and pay 30 bucks for it either, so I was just going to bring 2 (non glass) in a small lunch cooler and in my carry on (day bag). Has anyone done this? We have a private veranda and I want to go out on it one night while kids are sleeping, kick back and enjoy a drink at sea.
I will have to say...frozen tea cubes...i will have to remember that one!
