sorry, but no. not at all.
first off, your assessment of long island couldn't be further from accurate. i don't know where you're going with the "but it is in (sic) LI" comment, but for the record, long island has an obscene amount of disposal income. ever been to cold spring harbor? manhasset? any part of the gold coast? it's called that for a reason. and that's just the most affluent areas. the majority of areas are very firmly entrenched in middle-to-upper-middle class strata.
secondly, the people who commute to manhattan do just that: commute. they go in on the LIRR or NJ transit, take the subway, bus, cab or a very quick walk to work, then go back to penn station and come on home. usually in something that resembles a dead sprint. there's not a lot of leisurely walking around to explore if they can buy into bay lake tower or excess time to try to sit down and understand the annual dues.
like @
ParentsOf4 said, it makes no sense to rent out space anywhere (especially, of all places, manhattan) when you can use your own facilities rent-free AND be in better position to sell. all the closing of these locations mean are disney doesn't feel like wasting money on something that i'm sure brought in very little in terms of return on their investment.
