Flight of the Gibbon is so overpriced it is rediculous. If you like paying American prices in Thailand then go for them, and it isn't a double pricing deal, Thais get charged the same exhorborant prices. Single person for the 6 hour day package cost bt3800, with no discount for two people, and there are extra costs thrown in. The one hour package is only bt1800+ for one person, and not much is included. They are by far the most expensive day tour operation in Thailand, and it scares me to even think what this new package will cost.
