ok so... Bangkok is probably a no-go zone for us for safety sake.
Taking the train to Kanchanburi might not be possible from Bangkok unless things settle down. That area is not problematic now, but things can change quickly. Backup plans necessary.
Advice given during a to a response to a travelfish forum post: "
OPTION ONE: This means taking a taxi to the station from the airport hotel, and getting on the train outside of Bangkok.
TRAIN INFO/schedule to Kanchanburi. Taxi to Nakorn Pathom and get on train there. Maybe we can even get on at earlier stations (Talingchan or Salaya, which are before Nakorn Pathom).
OPTION TWO: Going to Ayutthaya doesn't make much sense for us, since we'll be going up there on our way north and it means a lot of back and forth/backtracking.
OPTION THREE: Or... skip Kanchanburi, which I'd rather not do since I want to stay in a fun river raft guesthouse and stick my feet into the water under the bridge on the river kwai ;)
SO all the way taxi, or taxi to a less riot-ey train station. OPTION ONE wins!
