We flew in the day before, because well when we booked the trip, Minnesota weather could have been a factor and we did not want to take a chance we would be late to the ship. It is nice to get in the day before, wind down from the flight, and just relax a bit.
We arrived at the Port of Tampa around 11:15 and had our group number at around 11:30, so it was quick. Carnival had the process down to a science. We were on board at a little after noon, and walking around exploring after lunch. Layout was pretty much identical as we expected to the Imagination that we had sailed in February. Overall, the process was quick, and didn't require us to wait much.
We had sailed the Imagination in February 2006 and enjoyed this trip about the same if not more. There was never a dull moment to be had onboard.
