This might sound like a starnge question, considering I am based on Koh Chang, but I normally fly out of Trat to BKK. I've been given differing information about this.

Basically, I need to get to Pattaya on Tuesday evening, but can't Really leave Koh chang until 4pm. So would mean that by the time i get the ferry, I'll be on the mailand at around 6pm. Does anyone have any idea, as to what time the last of the minivans depart from the ferry terminal? I was told today that the last one is at around 4pm?

check out www.iamkohchang.com its a a simple and accurate info site with stuff about the route you enquire about. As you live in KC you already know that the ferries departure time do not adhere to schedule. so perhaps you could leave KC earlier.
