I would recommend Gotoco

I would recommend Gotoco to a friend or family member as it is a great opportunity for people who can't afford expensive programs. It's also a great opportunity to see the other side of the world.
I had a great experience with the program as I thought all excursions and accommodations were very well organized and planned. I'm very happy with all the transport that was organized as well.
For me, the most enjoyable moments on the trip were visiting the railway in Kanchanaburi where I tried fried bananas for the first time (they were delicious!), and also the canal tour in Bangkok at the end of the trip.
