This is a truly beautiful temple with many lovely buildings and statues. The monks are naturaly warm, welcoming and tollerant. Ontop of this the temple offers some magnifigent views of the coast and Pattaya. It will not cost you anything and it is beutiful. 2 to 3 hours should be enough. You can get a taxi from Pattaya to take you, wait for you, and brink you back from 300 Baht, depending on time of day, how long your there and you negotiation skills.
It is a temple so you need to dress respectably, that means casual but covered. No bikini wear , short shorts or dresses, but no need to wear a suit , just be respectable.
