We just returned home from a Panama Canal cruise. (October, 2013) We had booked a zip line adventure and tour with Odessy Tours. Arrangements had been made with Alvaro. The other couples scheduled for our tour did not show up, but we got a first rate tour. There were 4 people on the zip line portion with 4 staff members assisting. We were given a ride to the top line and did not have to walk uphill as those who booked with Celebrity. Next was delicious lunch at a beachside restaurant and a tour of area highlights. It was a five star tour.
