I don't know... if they do this at all "right", I think they'll attract people who like the resort itself and are jazzed about the gondola access to two parks. This is decidedly NOT an SSR situation IMO.
I say this as an SSR owner since 2006 who has NEVER stayed at SSR since I bought.
As a BLT owner, too... "pining" is strong, but if gondola access proves to be VERY EFFICIENT AND PLEASANT, we would certainly try booking it once to check it out.
I'm not kidding when I say that I think A LOT DEPENDS ON HOW GOOD THIS GONDOLA SYSTEM PROVES TO BE.
