So you have to poop real bad on the Vegas Strip??

Aria - Through main entrance doors, turn immediately to the right. That is the closest bathroom. It's right by the hallway that leads to Deuce Lounge. The other closest one is to the left right past the coffee shop.

Mirage - Turn immediately to your right once you walk through the main doors. You'll see the mermaid statue with her tits out. Head right past the front desk area with the aquarium behind it amd walk towards 1OAK. There's a bathroom right across.

New York New York - Bottom floor entrance to the left of Nine Fine Irishmen, go to the left and head behind the escalators. There's lots of shitters in there. If you enter through the doors farther south (right side of Nine Fine Irishmen from the outside) immediately to your left are restrooms across from the sportsbook screens. Only a couple poop chairs here in the men's room so bear that in mind.

Paris - If you're walking up the Strip (towards the Stratosphere, down the Strip is towards Luxor) enter through the side door right by where the cars are pulling in and out. Straight ahead and to your right, you can pee or poop at the bathrooms.

Hooters - Walk through the main entrance and walk along the left hand side of the casino (past the bars and towards the actual Hooters restaurant) and you'll see the bathrooms there. If this is closed, walk to the very back of the casino and towards the right hand side, you'll see another place to plop plop.

Slots A Fun - Right next to Circus Circus and easier to head straight to to back and to the left past the bar. Places to pee and poop. Also the loosest slots on the Strip and pretty cheap drinks for the Strip.

Bally's - If you pass through the walkway from Paris to Bally's inside the casino, as soon as you reach the entrance to Bally's turn right and you'll see the bathrooms. Added bonus: Water fountains! Free water isn't something you can find at most casinos now. Save your water bottle and refill it here to save a buck from street vendors or three bucks from a casino store.

Venice - Walk through main doors. Once you get past foyer and into casino, head left and keep going straight until you see the bathrooms. Bonus: Another rare Vegas strip casino that has a water fountain. Refill bottles here to save money.

That's a few but I'll update. Hope that saves someone from pooping their pants one day!
