Two years into the game, Skedaddle seems primed for a classic hockey-stick adoption curve. One advantage of a charter bus is you are more likely to get like minded people aboard, by the natural grouping associated with finding and installing a particular app. Fifteen riders 48 hours prior to start are required or the ride will be cancelled. To help meet this requirement, consider the following points.
Ride start at popular point
Some rides I see start in the originator’s neighborhood, which may not be convenient to others. Just like Uber Pool, Lyft Line and the like, moving a block over (several blocks perhaps for Skedaddle) will give you a better chance at a desirable ride.
Some rides I see cost more than the equivalent Amtrak ticket plus Uber at both ends. I suppose the appeal in this case is getting fans of the particular event all together. Otherwise, maybe they had a bad train/bus experience motivating the move to charter bus sharing.
