First, the hotel is really compact in Las Vegas. Whenever you want to drive back to hotel, be careful to watch the entry. You may always miss the entry or drive into a wrong way.
Second, the Hotel Lobby is on 23rd floor (Yes, it is not on the first floor). Be prepare, there is no a decent lobby. Do not expect to see what you paid for. Yes, it is really cost to stay here. But the only make Waldorf Astoria stands out from other hotels is the price.
Third, You have to change elevator whenever you want to go to your room because there is no elevator direct to the guess rooms.
Fourth, be careful about the invoice after checked out. If you do not receive an invoice, ask for it. Check invoice carefully, they may charge more than you should pay.
Fifth, no Casinos , no shopping mall, no shows in the building. It is really inconvenience. It is even worse than MGM park, which may cost less than $60 per night.
More things to complain, but I believe the above comments help you make decision already.
