First trip to Aulani. What should I know...

[Plan Man]

But probably wouldn't think of?

Traffic in Honolulu is horrible.
Rental car lines can get long. I suggest a skip the counter option.
If you visit Pearl Harbor, I suggest you do it on a Sunday.
Don't go off the beaten path. Not all parts of Hawaii enjoy having tourists.
Finally, don't go chasing waterfalls.

EVERYTHING is double what you think.
Traffic is BAD
Locals go at a different pace and don't care that you're in a hurry.
