When my DD had an ear infection at Disney, we went to a clinic that was on a list the hotel gave me. They were going to charge me over $200 and my insurance wouldn't cover it, so I drove back to the Walgreens I passed on the way and $60 later we were out the door. Just Google Walgreens Take Care Clinic to find the closest one to where you are staying. They can take care of the standard illnesses such as strep, ear infection, flu test, etc.
