@RobertDavid,
There is a such thing as wasted space. If you don't believe me, go to Hersheypark. It's smaller than GADV, but it has way more rides because it takes better advantage of space. GADV's rides are spaced so far apart that it's crazy to imagine it's the largest amusement park in the world with the relatively low number of rides it has. And don't even get me started on the horrible layout that can be fixed easily.
There are plenty of other spots that "resemble parks" in the park - but that's not what GADV needs! An Antique Car ride would fit perfectly there, and that back area of Movietown would still be relatively empty for you to go sit in your "park" ... although if you wanted a park, you might just go to your local park instead of GADV. GADV is a theme park, which is for rides - why sit in a quiet, empty place when you're at a theme park when you can sit in front of a ride or rides and watch people?
