Adrian :
I found Suan Mokkh where meditation is taught in tradition of Buddhadassa Bhikku, whose books Culadasa recommands as further reading, but they only offer 10 day retreats.
This is why I am not sure of where to go.
Yes, I have read the book and found it to be extremly valuable.
Yo- I might be able to hook you up with more resources for a longer stay at Wat Suan Mokh. My teacher Dhammarato is homies with Ajahn Po, former abbot of the Wat and a leader in the lineage. Dhammarato is always trying to get me to do a lengthy retreat in Thailand and has lots of connections.
Are you interested?
