We will be going on the ruby princess through the panama canal next March. We have been to the panama canal once, we went to the Indian village in Panama, the safari in Costa Rica and tour of Columbia by bus. This time we are thinking about doing the boat tour through the canal. It is pricey, but has great reviews. I know I need to book this one before it sells out. Has anyone done that tour? Also the other two ports, any suggestions for independent tours? Thank you.
