In another location this would be a somewhat-above-average basic hotel. For Rehoboth it's very good. The good points:
Clean, clean, clean. Nice sized rooms. Lots of good towels. Nice shuttle to the beach. Breakfast included. Comfortable beds.
Breakfast is okay. A couple of cereals, yogurt (all with sugar), weak coffee, breads, NICE fruit, and a hot dish of minimal quality. Still, it's great not to have to go out and pay extra. Beds have nice linens, but use only a comforter that's too hot for summer weather. A top sheet would be nice - even though it wouldn't be European, I know.
There's a tiny pool. Our room was quiet, despite a gaggle of kids in the one adjoining.
In short, nice enough, but hardly luxurious. The $ you pay are because it's the beach. Fair enough, I guess.
