I normally would not take the time to write a review of a cruise but this situation warrants a few words. My wife and two teenage sons (ages 16 &17 ) booked the Navigator of the Seas because of the great reviews for teenage cruisers. This could possibly be our last family vacation for some time so we paid much more to go on this ship. That proved to be a costly mistake.
We found that a senior class trip was on the ship and this caused some problems with drinking. I have no problem with controlled drinking for 18 year old kids. They could be in Iraq fighting instead of cruising. I do have a problem with "out of control" drinking and that is what we experienced all week.
The group of 20-30 kids were drinking in every possible place on the ship. The elevators, chapel, and library were not off limits to this crowd. The ship security was not able to keep up with this group. They were buying beer for underage kids all week long. This put an additional worry on parents of 15-17 year old kids.
