Welcome to Orlando! I'm glad the trip went well.
Pet Bazzar on 436 carries reptiles, reptile supplies and live feeders. They usually stock up on Fridays because there is a rush every weekend.
Also, the Petlands around the area usually sell live rodents - you just have to ask because they keep them in the back. The Petsmarts and Petcos do not sell live but they may carry frozen - it's up to the store.
PM me if you have any other questions. Good luck!
