It looks like you are staying at Pop Century. They have Luggage Assistance instead of Bell Services.
This is actually a more efficient service for you!!
Check-in as early as you wish (6am is the earliest, i believe). Get your keycards, etc, and drop your luggage with luggage assistance, and head for the parks. Your luggage WILL BE automatically delivered to your room at some point during the day even if you are not there.
Also, on the day you check out, if you don't need to use the airline checkin service at the resort, call Luggage Assistance the night before and tell them you have xx number of bags to be picked up from room # xxxx at any time after xx:xx am. Stack all the bags by the door, (we always leave a few $s in tip on top), and head on out for the day. When you are ready to leave, bring your car around front, and call for your bags. No lugging them to the car!!
