We have free DDP, and of course the airfare, resort, and transportation are covered 45 days before we arrive, so this is JUST an answer as to how much we are actually budgeting for the 5 days we will be there:
Each of our three kids are getting one $50 giftcard for the trip, (not per day!), to spend any way they want (and I have VOWED to bite my tongue on their decisions!)
Over and above that, we are budgeting $100/day to cover the tip for our 1 table-service-per-day on the DDP, and other incidentals. I'm almost positive that we will use less that that each day. We are a family of 5 (4 "adults" and one "child"), so even if I estimate each TS meal at $175, that's an approx $32 tip (calculated at 18% - no debate needed

That will still leave nearly $70/day, or $350 for 5 days, for other things. We are not big souvenier people, and we won't have luggage space for a whole lot of stuff anyway.
