Having just arrived back from Orlando last weekend after a fortnight of full-immersion Disney (hotel, parks, free travel, the lot), it gives me a special glow to know that it makes me "downmarket" in Xenia's book.
It (Orlando, anyway) is much much more than just a theme park with rides. It is 4 different theme parks, 2 water parks, shopping and dining areas, parades, fireworks, characters, an animal reserve, and more. If you are not bothered about Disney and your dc's are equally unenthralled, go elsewhere.
I, too, don't get why some people feel the need to sneer. Different strokes... Oh, and I can (and will) just as happily do a week in Northumberland (or similar) and I'll be doing it in a 20 year old towing caravan. I have room in my life for a very broad range of experiences.
