Thanks everybody for the replies.

I'll be going alone. Sucks but more free time for myself to enjoy.

I'd figure to skip the luau. I'm sure there are alot places that serve luau food. Any recommendations?

I thought about hiking and I'm still deciding on it. I can sure use some physical activity during my stay as I have alot of food that I'm sure will need to be burned off.

Whats in North Shore?

As far as money goes, how much you think will last me a week for food, activities, etc.? The hotel, car need not to be worried.

And hows the weather around the first-second week of December?
