A: There are overland trips to Cambodia but for security reasons, and comfort, I strongly recommend taking a Thai flight to Phnom Phen ROH37. Travelling to Singapore by train is an exciting adventure, but a roundtrip by train is repetitious and time consuming. I suggest taking the train one way, with a stopover in Penang and perhaps Kuala Lumpur, depending upon how much time you have, and return by air. ROH has programmes for Penang, Kuala Lumpur and Singapore.
