One thing I guess thats important, Is the Poly hard to book in the 7 month window? For some reason I thought it was, but just for fun I tried to book christmas week 2015 and its still available. I figure if its available then, just a month out, I shouldn't have much trouble booking it any other time either.
Hard to say. Poly is still for sale and DVD (Disney Vacation Development) releases inventory to keep ahead of sales. You won't know until Poly sales are done in 3 yrs, give or take.
If you want a recent sample, when VGF sold out, studios during Nov/Dec are hard to book, even at 11 months. Having a guaranteed week there would make a real difference.
2 schools of thought on Poly:
1. With 360 studios avail and Poly owners looking for 1BRs they can't get at Poly, studios will be consistently avail.
2. With 25% of points sold for bungalows and the majority of point buyers buying points in the range of studio stays, those studios are going to be oversold by up to 25%. Combine that with DVC busy season and studios will be difficult to cone by at 11 months during peak times.
Who's right? We'll find out in 3 yrs.
Here's the thing, though. If studios are widely avail at 11 months in the Fall, having a fixed week won't hurt.
If studios are hard to book, that fixed week is priceless and, at that point (sold out), very difficult to get.
I think studios will be difficult at 11 months during DVC prime time. Not only is it a monorail resort, being a 2 min walk from the EPCOT monorail, it's a de facto EPCOT resort for F&W.
I think fixed weeks is a very good bet to take. I. Fact, I did.
