Please know I meant no disrespect toward you with my answers. EVERYONE needs a Thai Pass to get in to the country whether they come in with no visa and get 30 days or whether they buy a tourist visa before the come here and get stamped in for 60 days.
Ellie brings up a good point though, seeing as your parents are already coming for 50 days, getting them each a single entry tourist visa from the thai consulate in the UK using the online system before they come here would sure streamline their time here as they'd get stamped in for 60 days when they land AND if they did decide to stay a little more they'd have a whole 30 day extension they could get too giving them a total of 90.
Just a thought,.
They would apply for the visa here at this online portal
