Thanks for your input.
We have employed the services of Tong from Tong's tours to take s to Kanchanaburi for two days and we will leave from bkk and make first stop at Floating markets. I arranged the itinerary myself and there is a lot to take in given it's so short a trip, so I am fairly confident no EXTRAS can be squashed in. ( no uncle's or aunt's shops etc! )
I have heard of this happening, but Tong came highly reccommended. Since there are 6 of us to share costs which are pre determined it works out to be quite inexpensive.
Regards Jodie.
