I know the topic is out of the ordinary, but after reviewing a number of places thought I would make the inquiry here

i would def say off the strip and not one in a hotel for sure

The several I looked at were all off the strip; none inside any of the hotels.  It's better to get personal recommendations from the folks who live in LV.  I already have the piece picked out, the location of where I want it.  Now it's a matter of finding the right place and artist.

Visit and interview the artists that you are considering to find out if it's someone that does the type of artwork that you're looking for. See their previous work, portfolio and their personality and style.
And definitely check reviews  
Have fun !  Let us know who you pick

Off of Charleston & Maryland, all artist are pretty great but I highly recommend Chico or Jessie...

Ask for Kevin, he does great work

Making phone calls/inquiries and hopefully the selected artist has sufficient time to accept a short notice/walk-in appt.

I personally recommend Cameron Kelly.  

I will be in town next week and was thinking about getting some work done. thanks for bringing the topic up for discussion.

Normally I would use my current artist. However, there is a significance to the piece I selected and having it done in Vegas has personal relevance.

I have gotten one tattoo in Vegas. I have looked around but everywhere on the strip or at a major hotel are too high for me. I can get it done half the price in Ohio.  I may have to check out these places listed.

Find someone who does a style you like as well as seeing firsthand their work not just their portfolio. It's a common trend in the business to steal images just like here. How would you know if the tattooer did the piece he/she is taking credit for or not. A tattoo is forever and you should invest time and energy into finding someone who is good, not convenient or affordable.

He's done some really great work on my son and his friends.  
And! If you are not into loud guns, his is amazingly quiet.
