As for many cruisers, going through the Panama Canal was a bucket list cruise - it was great. We choose Celebrity because we love all the ships and the level of service. The Infinity is almost 20 years old but Celebrity has done a great job keeping it current. The MDR service with Edgar as our waiter and Mercy as Sommelier were excellent - the food was perfect for all of us. The stateroom service was great with Richard having our room ready by the time we returned from breakfast. We enjoyed several days by the pool and service at the pool was also good. As usual the service and food offered in Tuscan were fabulous. We saw all the ship Directors frequently out and about which was good especially as we had late afternoon coffee in Cafe Al Bacio. In our opinion the entertainment on Celebrity has improved quite a bit from previous years - some great cruise musicians including the house band. There wasn't anything on this cruise that we didn't love.
We were fortunate to have an aft cabin that a huge balcony for our transit through the Panama Canal. The room was in good condition.
