When I say it helps "local economies" I mean of course where one lives. That's a positive.
Around here, towns collect an income tax on employees who work in that town. The county and state split an 8% sales tax. If people want to go somewhere, of course they should. But there is a silver lining to people spending money at home instead of using it to fill a gas tank.
You see that as a POSITIVE? You're only interested in the increased tax revenue to the area? If so, you should be wanting outsiders spending their money in your area, so as to help the tax burden on the locals.
Quite a number of towns around here have a meals tax, in addition to the state sales tax, the idea being since they are "tourist" towns it is means of helping lessen the tax burden on the locals for the wear and tear on infrastructure and the use of town services. Of course the locals pay it as well, but it's better than our property taxes going up.
