There are many themed-hotels in Las Vegas. You have the MGM, New York New York, etc. Paris Hotel and Casino is one of the coolest because of the decoration. It is elegant but not too pretentious. The cobbled-stone walkway through the restaurants and shops is quaint. The buffet is one of the best in Vegas though expensive.
As far as the rooms, they are typical of Vegas hotel rooms. Once new, the rooms were beautiful. Now they are getting a little old and stale. Nevertheless, the hotel is still great for its reasonable prices.
