How to get there?
There are several ways to get to Kuala Lumpur (Malaysia). Considering the far distance from Malaysia and Vietnam, we chose to come there by air.
Air Asia - the biggest low cost carrier operating in VN - provides direct flight to KL. We booked 6 tickets 8 months ahead at an could-be-best-deal price, $50 round trip.
Good news! No delay at all. We arrived at the airport 1:30 h ahead of depart time. No many people on this flight to KL. Well, this time is no peak season at all. Several seats was being left blank at the rear of the jet. It's good!
I myself never tried the other way to get there e.g. bus, ferry...But somebody says that we can come there on bus / ferry via Thailand. May be next time.
