If you are in the Las Vegas area, definitely check out Roman Guitars which is a 5 minute drive away from the block where Palms, Bellagio (the one with the fountains), ARIA and Cosmo hotel/casinos are clustered together. One side of it is a museum/showcase area (some Dimebag pieces there for example) and the other is a store, and beyond that is their custom/repair shop. The guys and the overall vibe there are chill. It's a place I could easily see myself spending all day in. They have some amazing guitars there (saw a load of non-Explorer Hamers, an Ibanez Voyager and original Steinberger GTs on my recent stop by.) Just one hot electric after another in quite a spacious showroom. Their custom guitars are also out in the open to experience IRL which is a real treat if you only seen them on the internet since the early 00s, to finally be able to play one.
There is also Heartbreaker Guitars where you will find your heaven for PRS, Lowden, Rick Turner, Reverend, Eastman, Paoletti etc. Of all the places in Vegas to buy a really nice high-end acoustic (or electric?) they must be number one (they have so many brands of acoustic, some I have never heard of.) They carry Matchless, Soldano, PRS and Bogner Amps too. They have a beautiful showcase room/location however they are appointment only, it's north of the strip by the airport.
Sucks that Cowtown Guitars, who was ran by the guy that evaluated guitars on Pawn Stars, is no longer in business (or J&E because they had a great store and showroom too.) Have fun on your journey & safe travelin'.
Roman is still an operating shop? Holy shit. If they still have Abstract body blanks for real I might have to make a call.
