I agree with the previous poster about the weather...About bringing things onboard, it is all good.. They ask that you pack it in a carry on, in case of damage do your luggage, or someone else's..We usually bring a soft sided cooler with wine and some beer..Soft drinks are now free at the self-serve station, so that eliminated that need for us.....Water is also excellent, we bring one large bottle, and refill it...They do sell a water package, and that is to each their own, as the water truly is excellent...
Bringing food off on the islands, is a different matter, so inform yourself on those regulations, but bringing it on is OK..
