Koh Samui to Bangkok Destination Reviews

We had a great experience from booking the trip, to the traveling to the arrival. Staff were excellent all the way. The boat and bus were very clean. The bus driver was an excellent driver and it takes a lot for me to say that as I am a very nervous passenger.

A trip to drop four people off in Hua Hin added an hour and a half to the journey to Bangkok. Would suggest that Hua Hin people take an alternative bus or get a transfer taxi in the outskirts of Hua Hin to save the majority going to Bangkok the timely detour.

The food option was not upto the mark. Neither any specifications were asked for while making the booking. The tea/coffee service was good.

Global communication to be improved. I had to call by myself to get tickets as no one sent anything before my call. Tickets should be available once eveything is paid.
