I just got back from Manteo - I will have to hop to it and write my review.
The condos are two (some three) bedroom villas with a garage on the street level, then up a half flight of stairs to the living room, then a few more stairs to the kitchen, then another flight of stairs to the bedrooms, so you have to be the type of person not bothered by stairs. Our unit was right on the beach, I even had a duck waddle in the first time I opened the living room french doors (he shooed away easily enough).
We brought some DVD's with us and we all got a kick out of watching one on the resort's huge screen, in a private viewing room with really comfortable chairs and popcorn.
The weather should be fine, and that end of town is a little quieter than the downtown area where the Grand is located. However I would like to stay at the Grand someday as well. At Manteo there are three pools, a water slide, spa services and boat rentals that helped make our vacation lots of fun.
