Just came back from a couple days in Vegas. I stayed downtown at the Fitzgerald and stayed away from the Strip due to the municipal transit strike. You may want to take note that the bus is running on the strip, but the schedule is erratic now.
Enjoy your stay. If you do go downtown, try to do it in the evening for the Fremont Street Experiance show.
Free and worth the trip! If you go into the Fitzgerald at the far end closest to Neonopolis, you can take the escalator up to the second floor and watch the action from the public balcony. Great view!
