Yeah obviously the format I used that starts in January isnt cemented so if for example your 1st entry to Thailand was 1st March or early March, that format would allow you a 60 day visa exempt over Christmas in Thailand and the amount of days allowed (180) is dependant on the IO at the time I guess which isnt helpful at all as your risking flying to BKK from either UK or UAE not knowing if you're going to be turned away
Obviously a way around it would be to use one of your 2 month periods not at work, somehwere other than Thailand . . .
