I can't think of anything going on in town that would cause that. Anyway, I presume you've called the hotel directly and tried. Failing that if you really need to be downtown, the Westin Grand Bohemian is really nice. If you want to keep with the Marriott properties, there are a bunch over in what we locally refer to as "tourist-land"

. Some on International drive would be a 20 minute drive to downtown (off peak hours). Hope this helps a bit.
Best,
Joel
