We only use a credit card for the car rental (the CDW is covered that way), then it's all cash the rest of the way. Maybe not so big a deal this year, given the exchange rate of Dollar vs. Euro, but a lot of Grand Case restaurants do USD = to Euro when paying cash. As far as $, we do $500 per day if going to a casino after dinner, $300 if no casino. That said, we eat out ALL meals, with dinner being at higher-end restaurants ($100-200 per dinner for 2)and rent chairs and buy drinks at the beaches. You can spend a lot less per day or a lot more, depending on what floats your boat. Have a great time. Regards, Phil
