My Amazing Race SE Asia trip with Kristin was planned as a tight itinerary (Bali-Singapore-Vietnam-Cambodia-Malaysia-Bali). The first leg of the trip went fine, and were in Singapore's well-appointed international terminal by late Friday morning. After spending some time wandering the expansive airport, we caught a train, then a bus over to the LCCT (low-cost carrier terminal); this is where airlines such as Air Asia and Jetstar are situated, and it's definitely a step below the rest of the airport. When I tried to check-in for our flight to Vietnam, I was informed that a letter of invitation from the Vietnamese embassy was required (I didn't have, and couldn't get on short notice). Big problem.
Chang Beer; we spent about 150 bot (just over $5 US) and enjoyed them all happily while wandering the street. We soon retired to the guest house for a short sleep before starting our busy second travel day.
