In town for a funeral, need some nsa to clear my mind

Here over the weekend, hoping to find some discreet company, would rather not go with a pro unless I have to. What are the best casinos, night clubs... for this kind of thing? I heard Mandalay Bay is always ripe with out of town travellers, especially the milf types, also rehab comes highly recommended(I think that's the name) If all else fails what's the going rate for a pro per hour?
