Why not get a room at Allstars for $49 (see the Mousesaver Codes) and go directly there after your flight ... sign up for quick checkout. Then when you get up the next morning, just call the bellhops at Allstars and tell them you are moving to whatever resort where you are staying (I assume you're staying at a WDW resort), grab the WDW bus and head to the parks, and when you are done playing, just go to your new resort ... your luggage will be there waiting for you so all you need do is check in and call the new bellhop for your luggage. Once, the bellhop even had our luggage already in our new room - even before we got there and checked in.
We do this almost every time we go to WDW. We always come in late the night before, stay real cheap at Allstars the first night and then head to the parks fully rested the next morning. When we are done, we head to the Grand Floridian and our luggage is there waiting for us. It's so easy, no hazzle at all!
