Okay, then I would go with my recommendation that the OP try to check into her hotel, and if that is not possible, at least leave her luggage in their safe keeping.

So grab a luggage cart, get to the paid taxi stand (just outside of the customs control), they'll help you get your luggage to the taxi (they'll want a tip, of course) and ride on into the city.

If you can't get in to your room at the hotel, grab a book and go to a coffee shop nearby your hotel (wherever you are, there will be a coffee shop) and sit and people watch.

You could also walk in to a beauty salon and have your hair and nails done. I got mine done for $15. total. That would be relaxing and time consuming.

Also, contact your hotel and see if they can permit an early check in, no matter what you end up doing.

Have fun.
