I was hoping MG would come in with my "list" - cause I didn't save it.
I would recommend you make a list of the possible features of a resort that interest you. Here are some:
Length of contract
Location
Theme
Decor
Dues
Restaurants within walking distance
Parks within walking distance
Transportation
Parking
Point Value
Room Size
Availability of Special Views
Availability of Grand Villas
Availability of Dedicated Two Bedrooms
Hotel vs. Condo
Atmosphere (busy vs. laid back)
Pool
Perceived availabity at seven months
Buy in cost
Bed types in rooms (OKW studios have two Queens)
(and this is why I wanted my list, I can't remember the rest....but it probably doesn't make that much difference, this will get you started and there are others - childcare on site might make your list).
Now take the list and prioritize them. For some people, theming is VERY important - other people don't really care about theming. We never have a car at Disney, parking is a non issue, but for other people, its a big deal. I don't care about contract length - too old and not planning on passing this to my kids - for other people, its really important.
Now rate the resorts against the attributes - this will be very subjective. A lot of people believe the Epcot resorts have a great location, but there are certainly fans of SSRs proximity to DTD. Most people think SAB is the best pool (it is very cool) but we prefer a pool that its easier to watch kids in. Things like decor are terribly subjective - no accounting for taste. Also keep in mind that things do change - one of the reasons we didn't pick OKW was it didn't have a pool slide when we bought - it does now. BWVs bus transportation has been lousy, but its also been wonderful depending on how Disney is routing buses (and how lucky we get).
Now, multiply the weight against the rating, add them all up and look at the answer - your heart will tell you "Yes!" or "Oh, I really wanted ...." Go with your heart in the end.
Finally, if you can't make plans until a few months out "points is points" - pick a resort with low dues and/or a long contract length.
