Have you thought about renting a car, even for just one night. You'd be able to stop at DTD and grab a bite before checking in. If you rent with Alamo/National you could drop the car off at Car Care Center by the MK or at the Dolphin/Swan resort which is very close to EP and DHS. I often rent a car just to go to the store for a couple case of water, some snacks for the room and maybe a case of beer or wine. A bottle of water costs $2.50 at the parks and a case of similar sized bottle costs about $5 for 24 at a local store. We tend to go through about 40 bottles for 2 of us in a week, or 72 if the kids come. When I factor in car rental and gas, I always come out ahead renting a car.
