This is for the casino only. I cannot vouch for anything else.
They were very tolerant of my friends and I at 5am. They still served us alcohol and the $5 i spent on penny slots (which i was loudly renaming penny sluts. It was 5am people) lasted for what seemed a long while.
I will come back the next time I am stumbling drunk at 5am in downtown Las Vegas. Mwah!
