The hotel makes a lot of its shuttle service, which for most of the day is every 20 minutes, otherwise every 40. However, I waited over an hour, and another person over an hour and a half at the terminal 2 stop, and then shared a taxi, paid for by the hotel. Probably the shuttle got full in terminal 1, as the next morning the 4:40 am shuttle was full about 5 minutes before departure.
Otherwise, I was upgraded to a very nice room, spacious, nice bathroom and quiet.
