I like The Land
Listen To The Land was a great ride. It's not extremely different from the current incarnation, but it was still a little more enjoyable. Also, the guides talked during the entire ride as opposed to only during the greenhouse portion.
You can't forget Kitchen Kabaret. It speaks for itself.
Symbiosis didn't do much for me. I only saw it once, and that was because I wanted to tape it.
The Land Grille Room was innovative and fun. Instead of being a cute character meal, it used to be a real restaurant where you could quietly enjoy a meal and look out over the scenes of the boat ride. If it still existed, this would be one of the only full-service places I'd eat at while in the parks. That, my friends, says something
The Farmers Market was also the best fast food place in the park, if not WDW. Great selection, great food, great atmosphere.
After all this talk, I really miss the old Land pavilion
