You can take a taxi to one of the hotels, Paris for example, and then walk to other 4 or 5 hotels, and then head back to the airport, Just make sure to keep track of time, there are no clocks in the casinos and once inside it's hard to keep track of time . I recommend Paris, because from there you can walk to many hotels, vs if you go to MGM, Luxor or Excalibur it's a long walk to the center and were most on the excitement is. Good luck
