Another suggestion…is an AirB&B. I stayed at one in New Orleans and it was nice. I even enjoyed the early morning walk to the conference hotel. I don’t know what you might find close in Orlando, but just a suggestion. Also, check to make sure you will be reimbursed for AirB&B!
Or reach out to the ARCOS membership to see if anyone wants to share a room that they already have reserved. This cuts your hotel cost in half. I share a room and my roomie is awesome! 🙂
