We did our first B2B on the Horizon Sept 2021. We received a B2B photo and a bowl of fruit, no champagne. This trip we had to change cabins, so that was a little bit of a drag. Our second one was on the Magic in April 2023, we had the same cabin which was great and did receive fruit & champagne. Both these and the 2 we have booked in the future are all 14 days (8 + 6 and 7 + 7).
