I wanted to follow back here to relate my experiences with shipping. I sent one item USPS to Port Orleans French Quarter, and ordered from
Amazon Prime. The Amazon order shipped in 2 boxes as one of them was bottled water and heavy. When I arrived, the Cast Member who checked me in said "I show there are 3 boxes for you. Do you want Bell Services to bring them to your room?"
I'd sent the package from the Post Office and ordered from Amazon roughly 10 days before my arrival date. I don't know whether these went to the mail center first or not, nor do I know when they got to the resort. I just know that it worked perfectly when I allowed enough time to get there.
However, I
STRONGLY recommend printing out the shipping label with bar coding and having that available to put on any shipment that you plan to make from the resort to your house. I didn't, and when I got to registration to ship my package home, they were out of UPS Ground Labels. They labelled the label numerous times to send it Ground, called their shipping department (or whatever handles shipping), and logged it into a book to change the form to Ground when the labels came in.
When I got home and checked the card I'd used to hold the shipment, it had gone 2nd Day Air, with a corresponding very high charge.

In addition, it had my address crossed off, a different apartment number in sharpie on the label, and I only got it because I went to the office to claim it after it arrived 5 days after shipment with a 2nd Day charge.

I really only had myself to blame since I'd read here to bring a return label, and decided not to at the last minute.
I'll know better next time. Shipping there went perfectly, return shipment I need to handle myself with a prepaid label.
Next time....whenever that is...
