We also loved the lagoon the had where we were able to go snorkeling a couple times. The Big Island is the only one in Hawaii that doesn't allow beach front hotel properties, so the Hilton built a lagoon - with water flowing directly from the ocean - so we got to swim with these beautiful fish and sea turtles! I had never been snorkeling before but I just loved it. I wish we had a GoPro so we could have taken pictures of what we saw, but I suppose the images in my memory will have to suffice.
Another cool feature of the hotel was their dolphin lagoon. Talk about up close and personal - these dolphins were just hanging out showing off their tricks right in front you and for as long as you wanted to watch - which I sat there and watched a ton! We also got to FaceTime with Adam a few times while we were in that area and he got such a kick out of seeing them. I could swear one of them was even playing with and smiling at me. They are too cute!
You could tell this was definitely the resort to stay in if you had your kids with you - pools galore, water slides, a train that takes you from building to building & a boat you could take as well, parrots in the lobby, flamingos hanging out poolside, sharks (eek) etc. etc. etc. Maybe next time we'll bring Adam ;)
