Oh you are going to have so much fun! We found out on the big island that shopping in the hawaii section at wal mart was key as far as gifts. They had the same stuff as the airport but much cheaper. And I mean that when we went to the airport they had the same placematts, cups, frames etc.... If there is one on your island I highly suggest you check it out. unless you are looking for something different. Have a great vacation.
Oh I got a coconut lotion from wal mart and my neighbor saw it. She had bought the same lotion on line from some hawaiian gift site and paid twice as much as I did! She did not like hearing I got it at Wal Mart. Funny huh?
