I am sending a suitcase to the Peninsula in Chicago early next year-about a week before our arrival. I've made (actually, DavidO made these) advance arrangements with the concierge to accept it, and have the 2 items in it pressed for a function the next day. We will be coming in from a vacation and don't want to drag our formal clothes there with us.
It didn't seem to be an out-of-the-ordinary request for their conceirge.
