Thank you Pat. You said what was on my mind, but worded it much better than I probably would have.
The ship size is not the issue. It is the total number of passengers that are being allowed into port on any given day.
AND BTW, it should be noted that as a cruise passenger, I am not too thrilled about being in port with 6 other ships either! A resident can try to avoid the crowd, but wth am I supposed to do? I have things I wanted to see, 6 hours to do it, and that is where all the other ship's passengers are going as well!!!
So ultimately, in the end, everyone is negatively impacted when it gets overcrowded.
