I know someone that may still have a condo available at Shores of Panama - just down the street from the race venue. Very nice buidling - stayed tehre last year- couple minute walk from host hotel. He was planning to go up to volunteer, though so the reservation is only Friday - Tuesday. He paid the original deposit and has balance due of like $193 at check in. He is willing to switch the reservation and the only cost would be the remaining balance - he is out his deposit either way. but that would leave needing to find a place for Wed & Thursday. Let me know if you are interested and I will forwad you the contact information to get it worked out.
Lots of condos within walking distance. Most of the hotels are farther away and parking is always a challenge close to the venue. I saw a blurb on FB yesterday that the host hotel Boardwalk has rooms, but know the rooms are dumpy.
