Send it to the hotel, include your arrivial date, and your name.

Get proof of delivery, so you know if it got there or not.

Also call the hotel, there are many times stuff gets locked up in the manager's office, but he's not on duty when you check in so you can't get your stuff if you arrive too late, so make sure they know when you are coming, confirm it arrived, and will be available when you check in.

Don't have them put it in the room, if they do a room reassignment and don't remember they put your box in there or somebody else does it (say you get upgraded) another guest may think it's for them and open it by mistake.
