It'll vary by operator, but the standard-issue atrium-block ES paradigm has got to be 25 years old. A lot of them are tired. And bear in mind ES attracts a lot of kids, so endures more abuse. Every ES I'm in seems to have a roadtripping junior hockey team storming the place. But I stayed in one on the DTW perimeter last summer that broke that mold, it was a recently repurposed property with a lot of interesting design fillips, and thought it was terrific.
