Going back to the beginning of the story... The choice of Sussex and Kent as a holiday destination has struck me as weird right from the start of the podcast.
There's nothing wrong with choosing to go there on holiday but it's a bit odd. Most people who come to the UK from so far away want to see London, Oxford, Cambridge, or head further north to Scotland, the Lake District or York. Sussex/Kent is an unusual choice. Pretty enough, but mainly commuter towns for London. Lots of villages with tea shops and antiques centres but would it really be somewhere to occupy a visitor for 6 weeks from the middle/end of June through to the beginning of August? Personally, I don't think so.
There must have been another reason for basing yourself in that part of the UK. Whether it be a friend, a relationship, building links with a school or something else. Also as mentioned on the podcast the Eurostar train runs from Ashford (40km from Tunbridge Wells) through the Channel Tunnel and on into France or Belgium. There is a reason for her choosing that location for her holiday.
