Two years ago, we left Orlando and stayed on Daytona Beach for 1 night. We did not have reservations, but found a Super 8 right on the beach. We did not have a balcony room facing the ocean but when you stepped out on the balcony and looked to the left, you could see the ocean. It was reasonably priced and had a decent pool area. You would walk right out on to the beach and to the left was the pier area, where there are lots of things to do. Go-carts, carnival type, boardwalk atmosphere. very fun and the hotel was clean and nice. Had a microwave and minifridge.
We were going to stay there again this year, but decided to go to Daytona first just for the day before going to Orlando, and drive back on the West Coast and go to St. Pete Beach. I would definatly stay at the Super 8 again. I do not usually stay at Super 8's, I was leary. We even checked out some other hotels on the beach before choosing that one. If you stop, and ask the people working at the desk at the hotels, they will let you look at the rooms before deciding to stay there.
There are alot on the beach, if you want a nicer one, there is one, that has a lazy river that goes around the pool area, I saw it in the Daytona Book for Visitors and on Hotel Kingdom.com.
Have fun!
