There are so many variables that it's hard to get a clear picture but here are a few observations on resort price increase vs. dues increases. I used "regular" season rack rate pricing without considering taxes.
In 1997 a one bedroom at OKW was $305 - for 2007 it's $420. A 38% increase and an increase of $115 per night
OKW dues have gone from $3.14 to $4.40 in that period -- up $1.26 per point or 40%. Using a rough figure of 25 points for a 1 bedroom weeknight, cost is up $31.50 per night.
In 2000 a BWV 1 bedroom was $395, in 2007 it'll be $480 - up 22% & $185.
Dues for that period went from $3.94 to $4.85 or up $.91 and 23%. Figuring 30 per night for a 1 bedroom, that's an increase of $27.30 per night.
For a non-
DVC resort,
In 2001, CBR waterview regular season was $164, it's up 13% to $185
In 2001, GF lagoon view regular season was $425, it's up 18% to $500 per night.
We also have the influence of 9/11 working on these figures. DVC raised dues after 9/11 due in part to decreased interest rates and raised insurance costs. At the same time, WDW kept resort rates low to attract people back to traveling. I think we are just returning to some normalcy where dues are starting to stabilize again and resort prices are creeping back up.
