I had the first seat, in 1.80 so still not enough room for my legs. The roads are bumpy so it’s not a smooth ride. There are also stops along the way, at bus stations with lots of light so make sure you bring something to cover your eyes. The ac is on so make sure you bring a sweater and socks too! You get dinner, a snack and breakfast.
I got on the bus in Rayong. There was only 1 twenty minute stop just before ,10pm.
We got to Chiang mai at 09.30 am, which was an hour and a half late.
Overall the bus driver and staff on the bus were lovely and very helpful.
