I live in Ormond Beach (10 mins N of Daytona). We have a Hampton Inn (showing $499 a night) and a Sleep Inn at the Ormond exit (268) off I-95. Hotels book up VERY quickly, so you may have a hard time using points. You could also stay on the beach either in Ormond, Daytona, Daytona Shores, or Port Orange.

I would NOT suggest staying in Deland. 92 becomes a parking lot after the race, and without traffic it is a 30-35 min drive. That's not to say ISB won't be backed up, but I would not want a longer drive with the addition of all the traffic. Especially when you are tired and want to get back to your hotel and relax or sleep. I would try to stay as close to Daytona as you can.

Beachfront Properties (Ormond and Daytona) I would recommend:

Hilton Oceanfront
Holiday Inn Hotel and Suites
Holiday Inn Resort
Best Western Plus
Maverick Inn
Comfort Suites
Best Western Castillo del Sol
Quality Inn and Suites
La Quinta Inn and Suites
Shores Resort and Spa
Plaza Resort and Spa
Plaza Ocean Club
