No. I think you are missing the point.
^^^ This is also a horrible sign for Disney. The viewing areas for the parades and fireworks have the potential to become quite hostile, as I have witnessed myself around last holiday at Disney. There were two families viciously exchanging words and it almost came to blows over a parade spot.
This is a huge turn off for park guests like me. I purposely avoid the busier times of the year because I don't want to deal with this. If the tents are available I would rather have a tent.
Not to mention, the parks are getting more and more congested year round with extended Food and Wine and Free Dining, etc. -- slow times are quickly diminishing. It is a problem. So, the tents may provide a nice alternative for some guests.
I still don't know how Disney can pull this off. But, I am interested.
