I think crowds will be the tipping point for us as well. If you think about it, many of the issues people have with Disney these days dissipate with lower crowds. Wait times, FP availability, grumpy CMs....... it's all affected by the crowd level. And perhaps the ones who argue that nothing has changed lately are the ones who previously traveled at high crowd times so have not seen a change the way the ones used to traveling at low crowd times have.
I guess you feel the way I do. Our family avoids high crowds at any vacation destination. I don't want to be controlled by FP+ reservations to avoid long lines. I'd rather find a different vacation destination. This April will be our last visit to Orlando for a very long time. If I hadn't purchased airline tickets 3 months ago, April's trip would've been canceled. On the bright side, there are other places to visit if WDW is too crowded for us. Universal is a definite, but maybe SeaWorld would be another fun option.
I believe D instituted free dining at slower times to fill their resort rooms, but it has had that added effect of making the parks crowded all of the time. I also see reports of attractions being down and this is not for scheduled maintenance. I just don't think any amusement park venue was built so that maximum capacity could be continuously maintained.
I hope Disney's plans to convert unoccupied resort rooms to DVC will prompt them to stop offering the free dining. Then, maybe, sanity will be restored.
