Most of the time, it's just me, my wife, and my 7 year old, though I prefer to cook extra for leftovers. Also, I prefer to cook "indirect" with a basket of charcoal on either side. With the 22, I was constantly fighting for space.
I just got off the phone with Weber customer service, these pictures made me realize they forgot one of the "slide aside cover rollers" (the grey plastic piece the lid rolls on), and asked about a 26 inch Performer. She just giggled and said, "wouldn't that be great, wouldn't that be great".
Observations so far: This thing is big and heavy. The lid is much heavier then the 22. Miss the stability of a table/cart. The cooking level is about 3 inches "taller" than on my Platinum. Though I still wish it was about 3 more iches higher. (I'm about 6 foot)
