Here are a couple of random photos of Paris. One is of the carnival area just outside the Louvre grounds and the other is inside the Louvre.
I have been to Disneyland a good many times and I do not need to go back soon. The rides are fine and the experiences that copy real life adventures are interesting. I like to people watch, but I do not like long lines and cranky people in large numbers.
If I have to put up with the liabilities, I would rather be in Paris or London or Venice. There are crowds and gawking and people discovering new things, but what they are encountering is real. Certainly not everyone is there to learn something rather than to be entertained, but most have to come away with a deeper understanding of history.
Sure, there are Ferris wheels and merry-go-rounds - none bigger than the London Eye - but there are also first class museums and cafes.
Disneyland has its place and its fans. Yet, the most exciting rides I have been on are a gondola tram in the Alps and a boat down the Seine.
