How would we best logistically handle this situation?
My mom is booked solo on a 4 night cruise.
My son, my wife, and I want to join for the 4 night cruise AND also the 3 night cruise immediately before.
We're thinking it would be best to book one of us as the additional guest in my mom's room for the 4 nighter, which would require us to call and get added to the reservation. Then separately, we'd book the 3 night cruise for three people and the 4 night cruise for two people.
In this scenario, would the ship recognize that all three of us are back to back guests or would the one joining my mom's room have to disembark and re-check in.
