Booked online a room for one night. We stayed at the 20th gl of the Sky Tower. The room was bigger than most other chain hotels. The check-in & car parking were at different buildings. Due to the surrounding one-way streets setup, it took us a while to figure out.
The room cost was separated into two portions, one paid to the booking agency (Trip.com) at reservation & the other to the Circus Circus at check-in. At checkout, the hotel receipt showed an increase of $2.20 to the original cost when we booked online. No reason was given to us for why. So if you book the room similarly to what we did, do pay attention to the cost variation!
