You really need to call and ask, and find out when you can get those packages.
I once had something sent to a hotel, and the manager, thinking it was valuable, locked it somewhere in his office. I arrived Friday night, he was gone for the weekend, and not due back till Monday, and nobody could figure out how to unlock the closet he puts stuff in.
I know, very stupid procedures on their part to be sure.
It was work related, just had another one shipped to arrive on Saturday, but still.
So call ahead and find out what their specific procedures are.
