Similar to delivering to a PO Box.

Not really.

The reason FedEx and UPS can't deliver to Post Office Boxes is because they aren't the US Post Office. They can't drive their trucks into the US Post Office loading dock and unload their packages into the boxes inside the post offices. The only people who can do that are US Postal Service employees.

I don't know anything about hotel deliveries, but that would be a completely different thing than PO boxes, though. Not similar at all.
