Booked lodging for only 3 days of our 7 day vacation in AC.

Does anyone think it will be difficult to find a place to stay the rest of our vacation. We booked the first 3 days at Coco Beach and would like to check out other places while we are down there before booking for the rest of our stay.

We are traveling from 9/14 thru 9/21.

Any comments would be appreciated.
