Just thought I would tell you I just popped back to the UK last week and got a Category O multi trip visa from the Royal Thai Consulate in Hull. The visa gives me 90 days stay every entry and is valid for 12 months. Cost was £100
Talk about efficient - I was in the consulate for no more than 10 minutes. The taxi driver who took me to the consulate said it would be quick and that he would wait for me - I was wary of this and expected a lengthy wait - but he was right.
In fact I couldn't believe it - I have heard so many stories from people who have trouble getting a Cat O visa, I thought I would suffer the same.
