I am halfway back from Surin after picking up Nuth and Leon to bring them home to Koh Phangan.

I decided to use overnight sleeper trains for this little venture, on the way I took my usual 2nd class air-con lower bunk ticket but coming back with the baby I decided to try 1st class.

So we got a compartment to ourselves, 2 beds, wash basin and a properly sound proof carriage for about 200 Baht more than a 2nd class ticket.

I can definitely recommend this as an excellent way to travel around Thailand, really pretty stress free and cheap as chips!
