If you are traveling within the continental US, I recommend shipping anything you have ready via FedEx Ground. It takes 5 days to get there, but each box can weigh up to 70 pounds.
Andy and I usually ship at least 2 footlockers of stuff. Typically costs about $45 each way.
Just confirm the hotel will accept the boxes on your behalf before you do it
