OTOH, if you wanted a studio for 5 nights sun-thurs in early december, your 35 pt stay cost in 1994 has now increased by 43% to 50 pts. weeknight stays have taken a hit...but if you just stayed 2 nights on a weekend in early december at OKW, your 34 pt stay in 1994 dropped a bit to 26 pts.
if you typically stay for 7 nights, i doubt you'll see any big changes (although early dec is popular enough that it won't surprise me if they move it to a different season.)
timesharing definitely involves a risk of change. that's true. but for the most part, just buy a few extra (5-10%) and that should cover most of the small reallocations...
