As a current Poly1 owner, I actually want Poly2 to be a separate association. Poly1, with the proximity to all transportation options, has the equilibrium that we appreciate - studios only and easy to book (depending on the season) all the way up to ~7 months. This allows me to plan early, but not that early...It seems to me like more current owners want Poly 2 folded in (because of expanded room variety) and most non-owners interested in a direct purchase prefer they remain separated.
By introducing millions of points at Poly2, and given that studios are always the first to go, I often wonder if there would be more competition for the studios at Poly1 if it were the same association. If competition increases, it means that I'd have to plan at 11 months, on the dot, or risk not having the room I'd like. Of course, Poly1 has 360 studios, so it may not happen, but I would prefer not to chance it.
