^ The 60 days single entry + 30 day extension was always the plan. I've used that same visa before, but for a 50-something days stay (didn't need the extension).
Food for thought re the seven day 'get out of dodge' though, thanks. Ideally I'd like to have around 94 days in Thailand. When I apply for the initial 30 day extension though, are they going to want proof of my onward travel? Coz I'll only have a ticket for a flight 35 days later.
