I just returned yesterday from a great trip at Disneys Hilton Head Island Resort. We spent 6 nights there on a cash reservation, as we are not
DVC members. We had a two bedroom in building 22, which was a great location. Our favorite things that we did at the resort were "Secrets of the Marsh," meeting Shadow, watching the fireworks, watching "Peter Pan" outdoors under the stars, and the Pirate Party barbeque. Even though the barbeque is a bit overpriced, it was nice to just walk right up and get your food and not have to think about or wait for dinner. Outside the resort, we ate at One Hot Mama's and Skull Creek Boathouse which were both fantastic. We actually ordered takeout from Giuseppi's three different times because it had a large menu, was good, very convenient, and we didn't want to cook on vacation! We also ate at the Wreck of the Salty Dog which was not good food, but we did enjoy watching the tide roll in around the restaurant.
We took a dolphin cruise with Captain Mark that left out of Shelter Cove which was a lot of fun. This is a bigger boat which takes a larger group of people, but does have live narration. The scenery was great and we did see a few dolphins. It is only $16 for adults, and $8 for children which may be a more economical cruise for your family than the smaller, more personal dolphin boat trips. There are multiple tours daily, but no advance reservations and it is cash only because there is no ticket window. We ended up driving over to Shelter Cove for the cruise, because as my sister and I discovered walking over in the blazing heat, "objects across the marina are farther away than they appear!" Just a tip - if you are in one of the buildings away from the Live Oak Lodge facing the marsh and are walking to Shelter Cove, you are better off to walk down the back of the resort and then head for the marina, rather than walking along the marina on the resort side. It is shorter that way!
Our surprises of the trip were that we missed many activities at the resort because we wanted to spend the mornings and early afternoons on the beach. Also, I was under the impression that the section of the beach was "private" for resort guests, but that is far from the truth. The beach house is private, but the beach space is shared with many, many guests of the surrounding Palmetto Dunes resort. We also realized that there is even a separate outside window and patio seating where guests outside of the resort can order from Signals too! There was room on the beach for everyone especially at low tide, but it was not what I was expecting! Another thing, if your children are interested in the games on pirate night, you need to sign them up at the beginning as they quickly fill up. There is no control over how many activities that you can sign up for, and there were times that I definitely felt there should have been an age limit on the activities or different age grouping offered at different times. The preteens/teens sometimes dominated the younger ones participating, which did not seem fair.
I hope my information and perspective is as helpful to someone planning a trip as this thread was for me. Overall, we had a great time and I'm sure we'll return to Disney's HHI Resort. I think this vacation went by faster than any we have ever had. In the words of my 5 year old nephew, "it feels like we were only here for ten minutes!"
