We recently returned from 10 Sea Oak on our first trip to Hilton Head and couldn't have been more happy with our choice. The house is well kept with a great setup for a family vacation. We had 4 adults and 3 small children and could have easily fit another family in there as well. There are 3 bedrooms each with their own bathroom (2 upstairs, 1 on main floor), and a fourth bedroom with two trundle beds with a bathroom immediately in the hallway (main floor). Kids absolutely loved the deep, spacious pool - a key distinction from many other properties that may have a small, shallow pool that isn't very useful for kids. We paid for heat which got the pool temp to around 80 degrees, which was very nice for April. The beach is less than a minute walk on a well kept pier/walkway over the dunes. Also a great entertainment setup with cable/netflix/roku/dvd player, which was nice for the little ones to unwind at night with a movie or cartoon.
Another thing we appreciated is the ideal location. Located in South Forest Beach, you do not need to pass through a plantation gate to get to the house. Also, it's a very do-able bike ride to Coligny Circle, which is the hub of the beach area (groceries, restaurants, typical touristy stores, etc). My parents are in their mid-70s and were able to make this bike ride (easier for them on the bike path along south Forest Beach road, but they could also make it on the beach; it's about a 5-10 minute ride on the path). The nice thing is that even though you're a bike ride to the downtown area, the beach area in front of the house is not very busy. Also, there's a public pathway right next to the house which makes getting your bikes onto/off the beach very easy; but don't worry, there's not a lot of foot traffic on the path so you still feel very private in the pool and deck area. Just a fabulous place, great location, and we will definitely be going back to this house.
If we were forced to find some negatives it'd be that the refrigerator does not get that cold (they note this in the guestbook), and some of the windows are fairly weathered making them not very practical to open (something only relevant in spring/fall when its not too hot to open the windows). But these are very minor issues that did not prevent us from having a vacation to remember.
