Are you thinkin' Main Street is slowly de-volving into another DownTown Disney marketing model? Are the Victorian/Edwardian facades enough to evoke that 'hometown' turn-of-the-century feel? Seeing too many churro carts and neon glowstick vendors?
JosephTNielsen proposed a possible ride-type attraction be considered, and I say something should be done to keep alive the spirit of theme as well as the spirit of commerce (which seems lately to be getting the lion's share of the considerations).
What I propose is simple; it keeps the same storefronts (thereby keeping the same revenue generation potential), and at the same time creates new revenue opportunity in food sales: a Main Street Playhouse.
Vaudeville Theatre can only strengthen the MS thematic campaign, while adding a bit of excitement and flavor to an otherwise unappreciated area of the Park that is starving for something that guests can consider new; thus saving MS from being relegated to 'Disney Store' status.
Vaudeville comedy acts, stunts, music (maybe a Dapper Dan stage performance? Ragtime?), dance and melodrama will be the theatrical fare, as for the actual fare: small pre-prepared meals and drinks will be available as are in the 'Golden Horseshoe'.
With the popularity of the 'Billies in Frontierland, I believe the right combination of performance schedules, and the construction of a properly themed, well-appointed Playhouse where the Opera House now stands, could not only make this a success with the public, but also let MS shine a bit more than it has become used to over the years.
Some may argue that MS needs nothing, as it is a relaxing area of the Park, and should remain such a haven for the weary guest. Some would welcome a breath of fresh air for MS, but maybe not in the form of theatre productions...what is your desire for Main Street?
