We did the Circle Caribbean with B2B for the maiden Panama (new locks).
Boarding was faster than expected as the ship was not delayed at Customs/Coast Guard as long as expected from its transatlantic crossing. However for those of us that stayed aboard for the B2B turnaround the information given was incorrect, thier procedure/paperwork was not as expected and we were caged for over 20 minutes in the very hot boarding bridge because the ship was not ready for us. Bungled and frustrating experience.
We were aboard the CP in late March for the last cruise before its overhaul. We were impressed with the refurbishment. The ship is in excellent condition for its age (launched 2004), and we were really impressed with the new "Marketplace" buffet layout and the new design/decor of Steamers and Planks.
