We have been AKV owners since 2008. We love our home resort and would not want to change, in fact, we have an add-on in ROFR currently (third
small add-on in the past 2 years
). When we bought, we purchased enough points to stay in a 1BR savanna view for 7 days during Magic season. Within the first two years of ownership, there was a point re-allocation, and suddenly we were 4 points short for that room type. Plus, we found out that we really like to stay 8-9 days and often bring others, so we did not have enough points in the first place. Thus, the add-ons!
We have been able to stay at SSR, OKW, BWV and BLT in the past 4 years. All of those were made within the 7 months booking window. Our BWV stay was a 1BR boardwalk view which was booked a few days into the 7 month window for 3/9 - 3/14/12. We have not yet tried to get into VWL or BCV and we don't currently intend on going to VB or HHI, but that may change.
Since you like AKV, you should have no trouble getting into a 2BR that resort at 7 months most times of the year, other than perhaps Premiere season. At 7 months, you probably will never get the value or concierge level rooms. At this point in time, there are 2 BR standard views available less than 7 months from now.
As others have said, your DVC needs will change over the years and you may find different resorts that appeal to you for different reasons. If your good at planning far in advance, you have a very good chance of getting into another resort at 7 months, even if you have to use wait listing (which is how we got a BLT-LV studio in October last year).
Hang in there . . . your gonna love it!
