Here’s a much better idea Disney, I know you’re reading this:
1. A Princess and the Frog ride does not naturally fit in Frontierland, the location is slap bang between Peco Bills and Big Thunder.
2. Wouldn‘t it be better if Tiana takes you on the Liberty Bell river boat around the back of Tom Sawyer’s Island (as a short preshow of sorts). This could work similarly to Enchanted Tales with Belle, allowing a fairly large number of guests to interact with Tiana Up close but with a natural time limit built into the experience (cheaper).
3. The Liberty Bell docks at a 2nd North Dock area, where guests disembarked to an expansion pad on which the ride and Tiana’s restaurant is located.
4. An additional train station could be incorporated into the design of the area, giving guests a different way to get there and or travel back.
This scheme would truly be an addition to the Magic Kingdom of which everyone would be delighted, and beloved Splash Mountain could remain untouched.
