DH and I are going to Punta Cana in November for our 5 year anniversary. The resort is all inclusive and already paid for. I have money planned out for airport parking, airport food/snacks, tipping....but I'm not sure how much beyond that I should have. We don't own credit cards so that's not an option. Is there an amount we should aim for? We've never traveled out of the country as adults, so it's very new!

ETA: we will have some cash and use our debit cards as well.
