We stayed at the Marco Polo for $60 per night booked on Expedia, but we only stayed there the night we returned from REP at 7:00 pm and left next am for HKG because the Marco Polo is very convenient to the airport. We stayed in the Sheraton (cash and points $30) the nights we were actually seeing SGN and vicinity because you can walk to a lot of sights, restaurants, etc from there.
