The house was okay, though the living space was a little on the small side for our group of 6 adults and 3 kids - enough beds, but the kitchen was tight when cooking, and the living room seats 6 (which in fairness is obvious from the photos). We loved the turquoise Fiestaware, but the kitchen was missing some things like cookie sheets and some items were broken (whisk). The fridge is a very basic model which tends to freeze things in the very back when full. The bar stools are also not bar height, so if you are planning to have people sit there, their shoulders will be at bar height. The internet was in and out too, though our understanding is that this is a regular service problem throughout the 30A area and not specific to the property.
We had not stayed in Seacrest before, and really did not like it. The density of housing far exceeds the capacity of the pool and beach, so both were incredibly crowded at all times. Also, be prepared to wait a few hours after arrival to get your wristbands for access to the pool and beach. Seacrest Guest Services insists on delivering them to you personally - you can't pick them up - and since everyone checks in at the same time, it takes hours. We got ours after 2.5 hours. They also lock the gate that leads to the central pool & park-like area until 9 am, so no taking walks, except on the streets (which quickly flood in the rain btw). We wished they had used this locking mechanism when they shocked the pool and didn't put up any signs, resulting in some of my family members getting exposed to chemicals. The tram to the beach is convenient, with a stop right by the house, but the driver of my tram smelled of weed and got lost trying to get me back - I had to use Google Maps to help him out.
The good news is that there is public beach access 10 minutes away (Inlet Beach) and it's lovely. Parking is somewhat limited there, but we had no trouble parking early or late in the day. Speaking of parking, the driveway fits 2 cars, but there was plenty of on-street parking within a house or two of our house.
