I live in Winter Park (and work at Disney so it is a hike but not ridiculous) and I know of one above Winter Park.
Take I-4 toward east and get off at the Fairbanks Ave exit. Bear right at the end of the ramp and follow this road (it will turn from Fairbanks to Osceola to Aloma Ave...hint from the wise...watch your speed by Rollins College)
After about 6 miles, Aloma will run into Semoran Boulevard (route 436). Turn left (if you go right you will end up at the airport)
Go about 4.5 miles and Sams will be on your left side. The address of the Sams is 355 E Semoran Blvd, Fern Park FL 32730 if you want exact directions from your hotel.
Hope I was of some help!
