This is one of our favorite cruises and hope to do it again next year. Thye usually have a lecturer on the loud speaker as you tranist the canal. Very informative, but as was said lots of people and noise. We enjoyed it the most from our balcony in the early afternoon. I went up to the buffet got a nice plate of finger foods and such and we had a bottle of wine while we cruised thru. If you are on the side of the ship that you will pass other ships going thru at the same time, that can be fun also. We had someone on another ship hold up a big sign to us, got the banoculars out and it read" you are sinking"

we were being lowered at the time. If you check Discovery Cahnnel, every once in a while they have on Modern Marvels, the building of the canal. Absolutely amazing to see some of the old pictures and film.
