thanks so much for the reply

Can I ask if we need passport type photos with us for the visa? I had heard that from somebody but then can't find definite info anywhere. OH is researching guides and has a few recommended. I quite like the idea of a break over the hottest part of the day- about midday till 3pm?
One thing I've learned from my travels- don't try to do everything on one visit, its usually impossible. But then we have R@R time in Thailand afterwards
