I'm getting conflicting information regarding how Disney's Transfers from MCO (with a pre-arrival stay at Hyatt Regency) will affect our boarding time. Here is the overall situation. Last week we booked a great VGT rate for the Sept 22 2018 Eastern Caribbean Cruise, I checked in online before figuring out flights, hotels and transfers and selected the earliest available PAT, 12:15-12:30. I added flights and transfers through Disney the next morning, and on my own a pre-arrival night at Hyatt Regency MCO. Now under "Port Arrival Time" in online check-in it says - "You have purchased transportation through Disney Cruise Line and are not required to select a port arrival time." but on my Port Arrival Form it says "12:15 PM - 12:30 PM". My goal is to get on the ship as early as possible, both to relax and let me oldest get some pool time before things get busy, but also to sign up for activities, and MOST importantly try to get moved to main dining. Since we booked late pretty much all the onboard activities are fully booked. Disney insists my PAT will be tied to when I arrive because I am taking their transfers, but from these forums I am worried that will not be the case, and I will end up standing around the port for 2 hours with restless kids. Any recent advice? Tips?
