I think it's a bit different, as NY is a totally different experience, WDW and DLC and DLRP for that matter is essentially a very similar experience. To me nothing will top WDW, so I wouldn't even try (though reading cruise reports on this board, has really made me want to do that)
I loved NYC, but only went because I had a bit of a windfall, and was able to do it in the same year as a WDW holiday, I would never have chose to go on a holiday to somewhere other than WDW. My husband gets so annoyed at me, but I love WDW, why waste money on going on cheap package hols to europe, when for a few hundred pound more we can go on a holiday that I know I will love, rather than risk going somewhere that I won't like at all. When our kids grow up then I will consider trying new places, but until then, I would only consider going to Florida for my main holiday. That might seem really ignorant, but I'd rather be ignorant but happy that I've had a fantastic holiday, than be more enlightened to 'average' destinations.
Saying that, my uncle and his family went to DLRP two years ago, and are still complaining about how expensive it was, (but then they did have to get flights etc, as they live in Ayr) I know because the channel tunnel is inaccessible to us here, a lot of my friends find it cheaper to go to Florida on last minute deals than go to Paris.
