Never really stopped to count, thinking by the continents is more interesting. The actual # isn't as important as the experiences that you had in each place. Probably my favorite was a month in Australia. Many of the places I would not want to go back to again. Times have changed and not for the better. Only cruise I've done was a 10 day whale watch out of San Diego and into the Sea of Cortez. Only 35 people - very nice. Not sure I want to be with a few thousand people on a ship.
