In terms of the possible lack of security issue mentioned early in the thread. We just did airport check-in last week and the process went like this... At 8:30 Those waiting to check in went up in family groups to a check-in cast member behind a desk just like at the terminal. Passports and documents are shown. The cast member verifies photos are on file, (we were all returning cruisers) they present KTTW cards and lanyards, health questionaires are completed, they staple a card for the first bus (Mickey) to the document book. Your document book has a barcode that they scan to verify your name and that you purchased transfers so even if you do online check-in you will need your document book that they send in the mail. At 9:20 They call those with cards for the Mickey bus to line up. Everyone lines up and a cast member proceeds to check passports again and scans the barcode in the document again, matching up person with documents, that cast member also hands out Boarding Group Cards, everyone on the first bus got Boarding Group 2. At 9:30 We proceed to board the bus and they scan the barcode in the docs again to link us to the bus and confirm again that we paid for transfers. At 10:30 We arrive at the port, go through security and proceed upstairs to wait in the terminal. No further checks of documents were done at the terminal. So there are additional checks done at the airport after check-in to ensure the person checked in is the same person boarding the bus. This was our first time using DCL transfers and airport check in and it was great. Hopefully they will not discontinue this.
