We did B2Bs on the Dream in April. We had to meet at Evolution between 9:30-9:45. We were checked in and sat there for a bit. We were then walked off as a group through customs, using the face scanners. There were probably about 40 of us, maybe. We sat in the terminal and were told we would board at "exactly 11:30". We did need to check in there before that though, and then we sat until 11:30 when they told us we could board. I didn't mind that down time as my son had gotten married on the first cruise so I used that time going through pictures and getting/sending pictures from/to family...stuff we didn't have time to do while on the first cruise with everyone. Upon boarding, DH and I sat by the Cove pool (primo chair spot) before lunch, then continued relaxing there with a cocktail after lunch.
