I address brothels in general here along with others

In my opinion, the Bunny Ranch is highly over-rated as are most NV brothels. Bring a really fat billfold to get what is regularly available elsewhere for a quarter of the price. Unless you just want the mystique or bragging rights of having visited a legal NV brothel or are stuck in some remote little desert town, there are many, many other options available.
You mention Moonlight Bunny Ranch, so that means Reno/Carson area. There are many ranches just outside town, within 30 minutes of driving. It is also 10-12 hours away from Vegas.
