Best Place For Intensive Swimming Lessons

Hello,

I intend to spend two weeks in south-east Asia for improving my swimming technique and having some fun.

I can flight for free to one of those destinations: India, Indonesia, Malyasia, Thailand and Philippines.

Thailand seems the most obvious choice to me. 

So which place would you recommand considering that:

-i intend to REALLY improve my swimming technique and I will seek effective private coaching

-i  expect some lively nightlife (but I am not after paying-sex or recreational drugs)

-i like fine food

-i expect some wildlife opportunities in the area (i mean a trekking )-

-i HATE pollution but the closer to bankgok the better, say inside a 200 km radius

the critical point is finding a competent coach quickly,

ANy suggestions? thanks
