Really? The 2010 rollout was great? Not sure who you heard that from but it wasn't anyone on TUG, that's for sure.
Prior to the 2010 rollout there was rampant speculation for YEARS that a points system was coming with ALL of it fueled by sales reps who had no idea what they were talking about. The only "warning" we were given prior to 6/20/10 by MVC corporate was a couple of surveys that mentioned points options but didn't in any way state definitively that a points option was a done deal. The rollout itself came with no advance warning and consisted of changes to the owners' website shortly after midnight on that Sunday evening which included a blurb about a "new and exciting" program, and links to the legal docs that may as well have been written in Sanskrit for all the familiarity Marriott Weeks Owners could have been expected to have with an overlay points system.
Yep, the Vistana rollout isn't clean. It's difficult to navigate and there are obvious failures that need correcting, not at all limited to the many Club Dues issues. But you're living in an alternate universe if you think that the 6/20/10 Marriott Destination Club rollout was any easier for existing Marriott owners at the time. The reality is, Vistana owners/members are lightyears ahead of where Marriott owners/members were in 2010, and with the benefit of the experience of so many who came before you, your learning curve isn't nearly as steep.
I get it, it's understandable that people are ticked off at having to learn something new with a system that obviously wasn't tweaked to perfection prior to the rollout. But from where the 2010 Marriott owners sat, you have no idea how much worse it could be for you.
