On move day:
Call Bell Services and have them come pick-up your luggage and refrigerated items. Be sure to inform them that you have items to keep cold.
Tell them where you are transferring too.
If you are using one of the DPs, be sure to checkout of the Dolphin.
Check-in to your new resort.
Go do whatever you want that day.
After getting your room text and you are back in it (items are not at your new resort until 2 - 4 PM), call Bell Services to have the items delivered to your room.
NOTE: You must be in the room for the pick-up and delivery. Tips expected.
If you want to go straight to the parks and not go to the resort first to check-in and not get the text, yes you can do that.
