When i see all the tours to the tourist places in bkk,I know the boat trip and others are far away and take hrs to reach.When there, the thais charge alot to enter if u don,t agree you don,t enter.Then u have to get back to the centre with the same tuk tuk and then pay more or they leave.Heard this story last year from some tourist who got caught.Let say they were well and truly scammed
