You could probably place an Amazon order for pickup at an Amazon Locker (I think there are a couple close to the host hotels). Just a thought, but sorry you're having to deal with this rather than just being able to have fun at con.

EDIT: NO IDEA if it's any good, but this one was able to be delivered to me today, so maybe it could get to you?
