1. OK--so I've heard we can carry on a cooler (no ice) onboard with drinks. Is it one cooler per family or per person? 2. I know DCL offers free soda--how about tonic water? 3. Is wine duty free, too, or just liquor? And from what I've read, you can't consumer these onboard, correct? 4. Is there a price list for what drinks cost in the bars. etc.?
