Here is a great example... I own a Gold week at Frenchman's Cove and it is valued at only 2775pts. To stay at my home resort during most of the season I purchased would cost 2975 points (about 7% breakage). My parents own a Plat week, their value is 3650 but it would cost over 4000 to stay (over 10% breakage).
I am told by various sales reps and insiders at Interval that Frenchman's Cove has the highest trade value in the entire system. In fact, this was one of the major things the sales people push at the property (I've been on several tours over the past few years at this location). As an owner, I am able to fairly easily exchange my gold week every year for platinum time and string a two week trip with my parent's week. I've also been able to easily exchange to other high demand properties in peak season. This would not be even remotely possible with the new system.
I am now extremely worried along with other posters that with this crappy points system Marriott will be holding more weeks back and reduce exchange inventory in the interval system, thereby making it much more difficult to exchange back in to your home resort or other locations. Marriott severely undervalue many locations as they are not taking into account supply/demand of your home property.
