A McDonalds is a couple block norths of the Portifano Bay Resort on Kirkman road. It would take a good 10 minutes to walk from the hotel. The RPR is on the complete other side of the complex, way to far to walk. If you did, you'd walk along Universal Blvd, across the bridge, to I-Drive, and go from there. It would take you a good 20 minutes to do that. If you feel like walking, it can be done.
If you are not renting a car, have the driver stop at the Publix grocery store on the way. It's located about a mile north on Kirkman at the NW corner of Conroy road. Go inside, get a styrophone cooler in the beer isle, doughnuts, milk, juice, snacks, beer, and you can get ice at the hotel. When you leave, just leave the cooler next to the ice machines. You'll save a ton of money and most of all, time in the morning.
