We did it last year and every trip prior. I just read on a thread 3-4 days ago there is a trick to entering the shipping address. I don't remember what it was nor can I find the thread. I recall the thread saying there was a period in which Costco's website wasn't reading the address for Disney hotels, but it said that is no longer a problem. I just tried to do it, but the shipment screen is after the credit card information, so I didn't pursue it. It would be worth a try for sure! If you can't get it to work, then use Amazon or Staples.... Let us know if it works. good luck....
