I am heading to Aulani through Make A Wish grant with the family. Due to not booking this ourselves, I don't know the itinerary. I don't know what days have plans in them, so: I haven't booked any restaurants. Are these impossible to get on the fly? I didn't book a luau. These available last minute...like when we get there? Helicopter tour is on our bucket list. Any shot they are more affordable if I don't book till we get there? Can we rent a car while at the resort for a day or 2? Thanks in advance for any advice. We will be there in the end of June. Yikes!
