Another tourism related issue is the homeless population. There are not less houses, just less houses available for the residents.  The unenforceable illegal vacation rental market has removed hundreds if not thousands of units that used to be used by residents, which in turn kept neighborhoods just that, neighborhoods, not tourism centers.  My guess is it won't be much longer before the anger at loosing our hard earned lifestyle is unleashed on the unsuspecting tourists and/or tour industry.  That in turn could effect tourism much more than just controlling the overall number of visitors and what they are allowed to destroy.
