Thanks, it seems like a pretty significant price increase for a couple of extra things. Plus the second one being called "Extension" made me wonder if it was an add-on or an upgrade to an existing visa. They don't make things easy to follow.
I have another question. Does anyone know of any suitable health insurance for an elite visa? If I get the 20 year, I'd probably be looking at spending most of my time in Thailand but I won't be working. I don't know if I should get an open-ended travel (holiday insurance), some allow you to extend while you're travelling. Or whether a more formal annual health insurance policy would be more appropriate, and if so, with who?
