DS14 and I are going for 6 days and 7 nights. I planned on about $450 for food with us eating breakfast in the room each day and only 3 sit down meals. The rest will be counter service. I bring lots of snacks for the room as well. I plan on about $400 or so for the rest. It averages out to about $100 a day for everything. What I do is put $100 in an envelope for each day of the trip. Then, at the end of the day any money left over goes into a fun money envelope that I use for extras or hopefully take home to go toward my next trip a month after.
