WE took this excursion and it did not go smoothly as above reviews indicate. There can be problems. When we reached the location to board the boat (ferry?) to travel the canal there was a large cargo ship blocking the whole docking area. A delay of about an hour before an alternate boarding location was determined. Bus transferred us to new dock and boarded very late.
Definitely a trip to remember! Canal is fascinating, scenic and many historical stories. The food was as reported above, adequate to quell the hunger but nothing to rave about.
After the long delay,no one was in the best of moods. I need to sit in shade so found what i thought would be perfect location only to learn after a bit that the photographer was setting up right in the front of boat, just in front of where we were sitting, so it was impossible to get any good photos of our own without moving away. He was in the best location to take photos of people in front of the lock structures, but blocked such shots for everyone else.
Not sure if my final problem was for all these tours but on mine, the fumes from the fuel were overpowering, especially when floating low in channel .
The cruise ship waited for our bus to return and left very late for next location.
It left me wanting to do canal all over again on a higher level of ship. So new canal , ocean to ocean is on my bucket list.
