Hmm, so let me explain why it doesn't make us sad (and I completely respect your opinion on this). Have you actually sat on the grass? It is very natural feeling, and the type used is actually cooler than regular grass. I do understand that people miss the trees in the inner part of the hub. I get it as I've been there when they were there as well, having started going in 1978. However, one has to remember that the nightly shows today weren't nightly 20 or 30 years ago. Most weeks, even during the summer, the fireworks were only twice a week. Over the last several years, there were many complaints about the crowding in the hub for the fireworks, and how the trees were blocking the views, and how there was gridlock in the hub. Disney's answer was the expanded hub. While no answer to the problem was going to be perfect, we believe that the route they took was the best they could do under the circumstances. And please remember that when the trees were first planted, they didn't provide much shade either. It took years for them to grow up and provide the pictures that people post from the 90's. The new trees will do the same in the future.
Oh, and you do realize that while they don't have separate benches, they have built-in benches all along some of the low walls for people to sit? Are they under trees lie they used to be? Well, no, I agree that shade is missing, but since people wanted the nightly fireworks shows, there was little else they could do. They have at least replanted trees around the outside of the new hub, and when they grow in, it will be quite lush.
