Edit: I see William.already pointed out the RNC angle.

I'm sure you know this, but for the crowd, those dates are the Republican National Convention in Tampa.

Every room in town has long been booked by a delegation or event planner.

Assuming you're going for the convention or otherwise willing to pay inflated prices, PM me and I can give you the contact info for the guy our firm bought rooms from. I think he still has rooms available.
