Just make sure to make time to travel around a bit. I had friends who stayed at Waikoloa, and hated the island because they thought that the whole island looked like that. It is not the prettiest place, miles and miles and miles of lava fields in every direction, and that is all you see from the airport to the resorts. Lol, and its not the pretty kind of lava, it is the ugly brown stuff that looks like turned dirt. You are staying in 2 of the best hotels on the Island in my opinion though. Hapuna has a great beach and HUGE rooms. It is a massively spread out resort because the rooms are so big and all water facing. BI is my 2nd favorite after Oahu, but this year will be my first trip to Kauai, so will see if the order changes. This will be my 5th time on the BI. Once on Maui was enough for me.
