Yes, it is allowed. We shipped a box ahead to the WL last week. If you use UPS or FedEx the box will go directly to the resort, and there is no fee. If you use the US Postal Service, the box will go to a processing center first, and you may be charged a $5 fee when you retrieve it. We used UPS and the tracking info showed it arrived on Tuesday, and we arrived on Thursday. When we checked in the CM said, "Oh I see you have a package waiting"... and we were all set. :wave:
