With respect to our overall experience, my wife and I were extremely pleased given the price and our expectations. The plusses and minuses of the cruise have been well expressed by others, but I wish to add that I appreciated the respect given to me as a passenger - I was not constantly being upsold, cross-sold or pressured to buy things or otherwise spend money on board. All options were presented to me and I chose without feeling pressured. (One of my favourite purchases was the 7 bottles of wine package for $91. Excellent value for a well thought out variety of Italian, French and California reds, whites and a rose.)
Another observation. As a non-American, I met numerous American travellers who were polite, educated, well travelled and well spoken. They were in the majority and added great value to my enjoyment of the cruise. Unfortunately, there were also some Americans on board who truly fit the definition of "ugly". Ship's passengers come from all parts of society, and reflect all parts of society. We should all be careful not to stereotype passengers based on their country of origin.
And lastly, even though I love to eat and ate a lot, I was amazed by the number of obese passengers on board. There is truly an obesity epidemic and I am convinced that the long term health implications will be significant and negative.
