I don't know for certain about other resorts, but when we were at CSR in March, they didn't deliver to the room, but rather to the resort gift shop, where we could then pick it up. I asked the CM at the gift shop if this was done only at CSR or at the other resorts as well, and she said that WDW no longer delivers to the room at all, only to the resort gift shop.
Your best bet is to ask the CM upon check-in.
