I went to Galapagos, and they were thinking of limiting the total number of visitors. To me this make a lot of sense. You can't have hordes of people showing up, it'll wreck the place. I would do an auction, 10k or whatever highest bidders get to enter. A tourist attraction could then act like a monopoly and extract the maximum out of it, without straining themselves serving those customers (yeah I've got BT internet).
Granted, there will be a lot of politics about the distribution of that pie, but at least you can say you are getting the most out of the situation.
