Hi Mickeyd; I've done that cruise twice but I went Westbound, Ft. Lauderdale to Los Angeles, and I went on Princess. But I imagine the experience would be very similar. It is one of the best cruise experiences I've had. The Canal has to be seen up close to be fully appreciated. And it was a chance to see some new ports and countries. I don't know what HAL"s itinerary is; but we saw Costa Rica, Nicaragua and Guatemala, among others.
So yes, it's a cruise that I would recommend to everyone.
I would strongly suggest getting a balcony cabin for this cruise because it can get very crowded at the railings at the points of interest along the Canal. We spent most of the transit on our balcony, taking full advantage of room service.
