 It s a big hotel with so many rooms and my room happened to be in an area you need to go up and down the stairs for about 10minutes from the reception area I think you just have to enjoy this little adventure 
 Their system lets you choose the room you like very limited choice though one room per floor a couple of days in advance so you can check in before you actually arrive My selected room was ready and the notification came before 6AM so when I arrived at the hotel around 10 30AM I could pick up the key and enter the room right away which was great Check out is also done online so no waiting in the queue I think this works well for a hotel with so many rooms
