If you are looking for a place just to meditate and have plenty of seclusion, you may want to look at Na Uyana, in Sri Lanka. There is a strong emphasis on meditation and it is a huge place where you get given your own Kuti and have plenty of time fto yourself. There is good support and probably the most conducive place for western laymen to meditate. There is also instructions if you want to take them(Pa-Auk Tradition), but as far as I am aware they are optional. www.nauyana.org
If you are thinking about ordaination, then I would perhaps look to ordain in the west, and get some foundation in monasticism before embarking to SE Asia for meditation.
