For me, this will always be Las Vegas. Walking the strip my first time while at a conference was enlightening. Seeing all the American tropes that I'd seen in foreign media within a square kilometer and with my own eyes left me speechless.
Something really didn't mesh with me.Too much focus on fakery and "big" I guess. (Especially all that "Roman" and "greek" flair after having just toured the real deal a few weeks earlier)
So we took advantage of the cheap accomodation and visited the stunning places around it.
That's just my own take.
The monorail from Mandalay Bay to Bellagio is free, but it isn’t public transit.
