You unfortunately need to poop in Times Square? No problem. Walk into the Mariott Marquis, and head to the fifth floor. Don’t look around, don’t stop, dont take the elevators (theyre not like every other elevator). Just head for the escalators and walk it.
You’ll find clean, quiet, and large bathrooms just ready to be defiled by your disgusting filth.
[…] you can actually get away with quite a bit in NYC hotels as long as you look like you’re supposed to be there.
There’s some great advice in this thread.
