Not estoppel for sure.
It is called DOCUMENT REQUEST FORM and you get it from financial services. $55 for first week and $10 for each one thereafter.
If you got an EOY week, I would call for sure.
I called resale operation first last Thursday. They emailed me the 2 contracts same day. On Friday, I had it signed and notarized and in the mail. Monday they were at Marriott. Tuesday MSR sold. Wed MGV sold.
I know it is easy to sell 3BR MGV so I thought it will go first within a month or so but shadow ridge went first. Maybe it is a matter of communicating with the buyer.
I use these for II trading and frankly I think DSV II and Willow ridge are the best deals if you want to trade. MSR would have been as good but I like DSV location more in case I want to use it. I know others like MSR setup more which is a great property too.
Like others have reported, using these weeks (and Worldmark as well) in the past years I got multiple NCV in summer (inc. 4th of July week), FSA, MGO, MOW, MVO, MM1, MKO all in 2BR and even 2 of them are in 3BR. Most are prime seasons as well.
I am just lowering my week count from 8 weeks to 2 weeks/year as I always lock off. I simply overbought as buying Marriott weeks gets very addictive. Also we go every other year to Europe or other oversees locations where there is no Marriott timeshares so I end up with unused deposits.
