Room costs: moderate effects, depending on the magnitude of Trump's Holocaust II. Labor costs may go WAY up, as Vegas relies on immigrant labor to keep its hotels running. We'll see.
Food: this is the real biggie, as Vegas imports thousands of tons of food from Mexico every day. Hope there are no tomatoes in your meals. Or beef. Or avocados.
Transportation: Trump's I Hate Canada tax will increase gasoline and jet fuel prices...the exact amount is yet to be determined, but economists estimate 10 to 15 percent, which will of course be passed on to consumers.
Gambling: a drop in visitation caused by backlashes against Trump's I Hate Everybody campaign may make it a little tougher for the casinos to make money.
So if you come to Vegas and you voted for the Orange Turd...don't complain about high prices. You got exactly what you wanted.
