So with the casinos trying so hard to stop free drinks....
If you like something like Mikes hard lemonade which is in many bright colors you can put it in an empty gatorade plastic bottle. It looks like gatorade, but it isnt and with the temps in las vegas sometimes around 100 degrees drinking a big bottle of "gatorade" in a casino does not look odd.
I dont like giving money to MGM resorts or Caesars resorts. They offer bad games and charge for parking. Unacceptable. So if in that neighborhood, instead of putting a $20 in a mchine at the bar if you are trying to scalp out a free drink and hoping to stay even for a little while and cash out, buy some Mikes at one of the convenience stores or pharmacies outside the casinos and dump it in a gatorade bottle. Also works downtown walking around especially if wanting to play a non bar machine but want a drink until cocktail waitress comes around. Nobody finds your "gatorade" unusual. Its a desert...
