I just did my first B2B on the Allure 2 weeks ago. I went to GS to make sure they had me on the consecutive cruiser list. I was only moving 6 cabins down so I saw when the people left and rolled my bag to the new cabin myself. They will move your bags for you. There was a B2B lunch but I didn't attend as I had friends boarding on the second leg right around the same time as the luncheon We had to disembark and go thru facial recognition in the terminal then sat for around 10 minutes and then reboarded There will be a letter in your stateroom
