I like this idea; It would have been far more effective in getting people to wander between the Marketplace and West Side than the parking lot sidewalk.
I'd have probably put the pathway in the parking lot in what would have effectively been an extension of the Marketplace itself, building more (small) shops along the waterway linking McDonald's/T-Rex with Planet Hollywood. No need to walk past P.I. if the Marketplace wraps around it, seamlessly transitioning into the West Side. Shoppers would have looked across the narrow canal at P.I., but Club patrons and Marketplace shoppers would have largely been seperated.
Problem is such ideas would have cost money and involved taking a risk, when it is so much easier to just close the clubs down and rent the space out to third party tenants ("bold new vision"). Of course, its obvious how well that brilliant plan worked out (and you cannot only blame the economy). Wonder if whomever came up with that winning idea got a bonus out of it?
