Well with Cars area and Big Thunder as the only piece of Frontierland, Tiana makes literally no sense in it's current location either...they have added nothing to support that you are now in Louisiana...considering you just went by some old Western buildings...The Splash red clay rockwork blended a little better with the red rocks of Big Thunder... It is all just becoming a thematic mess...
Agreed. I’m hoping this is addressed with the cars attraction and not made worse. I think the artwork we’ve seen was somewhat rushed (with no details on the 2nd attraction that seems likely) - that’s why I still have a sliver of hope for the riverboat.
Even without the riverboat I hope they attempt to tie this all together somehow and not just plop some rocks down and say “look more stuff!”
To me, the most effective way to mostly fix this would be to:
1. Make Cars and Big Thunder the official Frontierland with the land's new borders being the very edge of Cars on both the Liberty Square side and the former waterfront side, and create a hard physical border out of rock work or something to somewhat isolate it to itself.
2. Turn that waterfront (where Tall Tale Cafe) is into a New Orleans themed corridor that leads down to TBA. You could even leave a little bit of the former river up front, park the Liberty Belle there (maybe even turn it into a Tiana M&G location), and have rocks on the other side of the water/boat to act as a separation between that corridor and Cars.
3. Leave the pathway by TBA that heads to BTM there, but dress it up a little more to make it be a proper land transition. The train station could still be a part of Frontierland with this arrangement.
This would create an isolated and good sized Frontierland, leave Liberty Square, create a MK version of New Orleans Square (but more like a waterfront corridor), and still allow them to make the land bridge back there.
Of course this option would require them to completely redo the facades along the water front and turn Tall Tale Cafe officially into Tiana's Palace, and I just don't think they're willing to drop the cash on that even if it solves that entire area's thematic clashing.
