Sunday night at midnight is the end of the Huntsville Workshop special rate blocked rooms at $80 for double beds. They are sold out of king beds unless they have any of the $100 suite king rooms left, which I doubt. I do not know what the rates will go to after monday morning if you book later. If you are even thinking of coming and you are waiting a few days to register, at least book your hotel room today do you have one. You can reserve rooms on the website under accommodations.
