I have had parcels delivered to my hotel from both Land's End and L.L. Bean. When you place the order just have the mail order company add the date you are checking into the hotel to the Label. I always phone the mail order companies direct to ask them about shipping dates to insure the parcel arrives during my stay. They are usually very cooperative and helpful with timing the delivery just right! It also doesn't hurt to phone the Disney Hotel and ask them to flag your reservation that you are expecting a parcel!
Yes! Yes! Yes! This saved paying duty, especially from disneyshopping.com, because it usually cost me more for duty than the outlet items I order. The parcel actually arrived at OKW a week and a half before we arrived (they had $5 shipping when I ordered a bit too early!), and the resort held it for me until we arrived. So happy shopping - planning on doing again this May for my DDs birthday gifts.
