solid 3.5 stars. In fact, depending on your bus driver, it's a 4-star if you get that funny driver who speaks hello/thank in 6 or different languages lol.
Buses are sure packed yet very spacious, comfortable, even the double-deckers.
Went on a whim after deciding walking back to the lobby's taxi area would be too burdensome in the chilly weather lol.
Getting the one-day unlimited pass sure was worth it, used it 3 times.
