I'm not going till February but this is where I plan on making an appointment prior to my flight back (Rhode island)
AdventHealth Centra Care Lake Buena Vista
12500 S Apopka Vineland Road
Orlando, FL 32836
They do rapid testing (15 minutes) and is open 24/7 which is convenient since I plan on doing this two day before my flight home. Unfortunately the cost is $180 since its mainly for travel (without symptoms)
Be careful about rapid testing, which is usually an antigen test, where travel usually require a PCR test instead,
