Yo, here's a few tips.
The dollar theater in town - well the only one - is
Wallace Theaters at Restaurant Row. Their matinees are 50 cents!
I am sure you probably know this already, but the local "alternative" newspaper is the
Honolulu Weekly. If you go on any hikes, slather on the mosquito repellant - there will be lots of them.
Get a Hawaii ID ASAP too. Why? There are a lot of places that give residents discounts - like if you go snorkeling at Hanauma Bay, you get in free, visitors pay, I think $3. Hanauma Bay is awesome - it's a fish preserve and there are just tons of fishes there. You can go snorkeling there at night on certain days. I tried that once, but the fish got really scared of the flashlights, so that was disappointing.
If you got questions about being here, I'll answer them as best I can.
