Round trip ticket to Bangkok. 3 months is enough to head up to Chiang Mai, take the slow boat down the Mekong into Laos, cross into Vietnam, make your way South then into Cambodia, then park it at Tonsai beach in Southern Thailand until your time's up or you decide to blow off whatever it was you were heading back for and extend your trip out to an entire year. If you haven't done that already, then there is absolutely nothing else in this world (short of fathering a child) that will be as engrossing or life changing. Book it today.
