There's an understatement! My girls just loved the airport - it's a bunch of fake grass huts, you exit the plane from a stairway ramp onto the tarmac and it shouldn't take you more than 30 seconds to walk from one side of the airport to the other.

The interisland flights are open seating, meaning you get in line and take whatever seat is available so when you get off the first flight, get in line for the second as soon as you can - they start lining up 15-20 minutes in advance.
