Have done the historic locks 3 times from Atlantic to Pacific, so joined friends to see the new locks going from Pacific to Atlantic. Somehow, I was expecting more differences between the old & new locks, but either way it’s quite the engineering marvel even if you’re not too technically inclined. Did enjoy the stop at Fuerte Amador on the Pacific side and being able to get off to see the visitor’s center, not an option on any of our previous trips. The other ports were enjoyable, didn’t feel overly crowded like on some other itineraries where there are often multiple ships in port. This was our second Princess cruise, we have cruised more often on Royal Caribbean and Celebrity. I like the “vibe” on Princess, in this case there were very few young kids on board which made it more relaxing. Emerald appears well maintained, staff were generally pleasant and helpful, there were a few outstanding crew members that will go far if Princess is smart enough to recognize their skills. We traveled with 3 friends, plenty to do with or without traveling companions.
