Greetings!

Can some kind, well-informed soul confirm if my understanding of the current visa on arrival condition (and possible extension) is correct?

I plan to spend 30 days in Pattaya in December/ January. On arrival, I will receive a 30-day visa. If I decide to make a short visit to Cambodia by air before my 30-day visa expires, do I receive a new 30-day visa on arrival when I fly back into Thailand, thus allowing me to stay longer in Thailand than 30 days?

On the other hand, I understand that I can obtain a 60-day visa from the Thai Embassy in London but there is a fee and some paperwork to complete.

Finally, if I enter on the standard 30-day visa on arrival is it possible to obtain a short extension - say by a further two weeks - at the immigration office in Pattaya for a fee?

Thanks in anticipation.
