I can't imagine they'd transport well at all, and I don't think you can just pick a bunch of them up. You can only order them to be served with your meal at CRT or the GF restaurants. I suppose you could make an ADR for one of those restaurants,pre-order the slippers, and while you ate, ask for them to wrap up the slippers to go, but I'm not even certain they'd be willing to do that. They're really meant to be eaten at the restaurant.
