I presume this strongly depends on the location -- a slightly marginal location where the natural state is not particularly crowded would have a strong incentive to pull in more customers, even campers, to give it a vibe of "the place to be." Such locations probably have lower rents as well, and can afford larger spaces. However places in prime locations and densely populated neighborhoods can be packed 95% of the time, whatever they do. For them, the tradeoffs are very different...
