Maybe because you are so close to check in date they mailed them directly to the resort. You can call IT and they can tell you were they shipped to.
I got an email saying mine shipped, there is no longer any shipping information on the site, but the tracking number is coming here.
Also, my BIL who did not previously have a MDE account, got his UPS "invitation" delivered to my house today. I had all the stuff for the trip sent to me because I'm the coordintating the whole trip. I got their MBs set up today.
