what about a change in the number of points for each type of villa? It has seemed to be out of proportion for 1 BR to be double studio but since the only timeshare I am familiar with is DVC
For both Hilton and Hyatt, it's, more or less, a studio is 1/3 the points of a 2br, and a 1br is 2/3 the points of a 2br, and a 1br is twice the points of a studio.
For Marriott, it varies a little bit more, and many of their resorts consist of 2br's only. But, more or less, a 1br is about 2/3 the points of a 2br, and a studio is about 45-50% of a 2br, or about 75-80% the points of a 1br. IMO, a studio is not a very good use of points at Marriott since a 1br can be had for a small amount of additional points. But, as I said, Marriott varies somewhat from resort to resort.
Marriott example for Grande Vista in Orlando for early December time period:
weekday: 100 studio, 125 1br, 200 2br
weekend: 225 studio, 300 1br, 450 2br
(You'll also notice the high point differential between weekday and weekend)
