I am very glad that we own where we're happy to return each year -- Maui Ocean Club (2 weeks) and Canyon Villas (PHX)(1 week). We've been using an old Grande Vista week to pair woth CV to get 13 month booking rights, and bought Lakeshore Reserve planning to use it every other year or so, or rent it out. We have liberally traded GV for MR points, occasionally deposited and traded through II over the years since our first MVCI purchase in 1995 (Kauai Beach Club, which Marriott took in trade from us in 2007 or 2008 for our MOC purchase at much more than we had paid for it - a rarity, I suspect) When we trade, it is almost always to other top-trading properties.

All that said, I have NO interest in the new points system. I suspect most owners of Platinum weeks in premium locations, esp. those (like us) who bought from Marriott, will NOT join, though there will be outright revolt if and when Marriott cuts the MR link. (We have kids living outside the US, so the MR points have been very useful.) Our GV property will be worth little, but it was paid off long ago, and I expect we'll be able to rent it to cover the maintenance fee. If Marriott inventory available through II dries up, so be it - going back to Maui and PHX every year isn't so bad, especially since those are working vacations, and we'll find a use for the FL weeks.

However, this is only first impression - I reserve the right to change my mind completely after I delve into the materials more thoroughly!
