Yes. Believe we got a letter and also an email. However IIRC, I read about the increase here on the DVC Forum before I got either the letter or the email notice. Think members had a couple of months notice (or maybe a little more than that). Maybe someone else will remember for sure.
There have been some posts before with the historical information on pricing and price increases with regards to the points and maintenance fees as well.
Might want to try and get the 'search' function going on that one though because it's been a while since I've seen them.
