How would I change mainstreet?
1. Add a Penny Arcade. That would be really cool for a "turn of the century" main street!
2. I'd love to be able to have someplace to watch some classic mickey cartoons? Maybe a cinema location someplace where we can go into the old-timey movie theater and watch some of those old black and white mickey shorts all around us?
3. I don't know how many main streets have just a single T Intersection. Why not just have that one intersection turn into a complete cross street? It'd help break up the other side of the street a bit, and also give us a cool place to maybe have some benches, or a popcorn vendor? maybe another silhouette or caricature artist. OH! And flowers! A balloons for the kids.
4. I'm thinking a Bank on Mainstreet would be helpful too. I'm sure the decor of a classic turn-of-the-century bank interior would look awesome. It would also give people a place they can withdraw some money if they need too, or even maybe buy some Disney Dollars or gift cards or other small-ish trinkets?
5. ok... I know it's not much, but it's a start. IMHO it'd really help give Main Street more of a....well... Main Street type vibe, and less of the "I gotta go this way to get into/out of the park" vibe.
