Check-in took 45 minutes, there was a very long line. To their credit the Check-out line was on the first floor and another desh on Floor 2 took the Registrations. The Hotel is massive with 7,000 hotel rooms, theatres, casino, restaurants and shops. It is the largest hotel in the US. The service was very good, the rooms are all suites the only problem was orientation since the hotel is like a city in itself.
