I love staying at Embassy Suites for many reasons already mentioned.
Probably the most unusual/interesting/valuable ES experience was sort of a competition between the really nice hotel bar and the manager's reception (I think Dallas maybe). The bar had happy hour (2 for 1) from 4:00pm til 6:00pm with yummy hot & cold appetizers. Hubby & I went to the bar at 5:00pm, bought a round and snacked on delicious appetizers. Left a nice tip & walked over the the manager's reception to enjoy!
Worst snacks at an ES establishment was stale popcorn at a West Palm Beach ES (of all places).
