Day-Tripper Bans, A Step Forward or Well-Intentioned Folly?

I just came across this article and felt that it would be a great discussion point for this blog. Overcrowded Venice may ban day-trippers

Apparently, Venice is considering the exclusion of 70% of its tourists: the day-trippers. A proposal to only allow those with pre-booked hotel stays is being backed by Enrico Mingardi, Venice's head of Public Transportation. I think I sense a collaboration coming on.

Anyway, please leave a comment about this. What do you think? Is this a good turn-around to help Venice reclaim their economy or will it only drive away mainland Italians and steepen the slope to turning the city into Disney Italia? I'm going to put up a poll as well, so please vote!
