The last owners update we attended will be the LAST owners update we attend.
To start with, the "incentives" for attending weren't worth the effort to pick them up. They were mostly discounts off shows that I could find without the pain of going through a sales presentation. We went because we had a few questions about our ownership and we wanted to be updated on enhancements and the construction schedule of our resort (we own at the LV Strip location). We also had some mild interest in upgrading our points to a penthouse unit but, they said they weren't allowing "upgrades" anymore and went on to attempt to sell us 9,000 more points that we didn't want or need.
Instead of a low key update with sales presentation, we were treated to the full court press, just like we'd walked in off the street. This was complete with the trial membership close from the manager (trail membership? We are already owners).
In the end we turned down the "free" gifts as there wasn't anything we really wanted. I'm not sure the grill at the gifting desk knew quite how to react when I told her we didn't want anything and turned down her offer for a couple of buffets at the Flamingo (been there, done that).
Maybe different sites handle owners updates differently but, based on our last experience at our home resort, we don't ever plan on attending one again.
