it was chosen as a tribute to Missouri, Walt's homestate. As was Mainstreet, USA. I think this is a sign that generations are moving on...those with emotional ties to the Mark Twain stuff are retired if they're still around. I'd guess that major overhauls were an emotional issue- until now.
I have to say, comparing the island at DLR to the one at WDW...well, there's nothing there! I was very disappointed with the one at DLR because it just didn't engage the kids. They could have had things to do that were of interest, but when we were there last year all it offered were trails...trails with not much to see and nothing to do along the way. I think the one at WDW was much more engaging. Being able to grab a PBJ and eat dockside was one of our favorite things about it. We ate lunch there two out of the five days we were there!
As for palm trees...well, could they get mangroves to grow? They'd have to change the water from fresh water to salt water...but it would at least be true to New Orleans. That would be okay for the riverboat...after all, NO was the destination.
An improved theme...any theme...was much called for. As to the question of whether my kids refuse to play at local parks...that's comparing apples and oranges. It's 5 a five minute drive to the park and the only cost is the gas. If I'm saving for years, traveling 1500 miles, and plunking down more than a month's take-home-pay in return for 5 days of entertainment, those days had better be GOOD!!!!
