Lance first visited Greece in April 1982, travelling to Plakias in southern Crete. Following another visit to Plakias in April 1983, he initiated and led guided botanical walks there from 1984 onwards, for SunMed Holidays. After giving up the day job in an insurance office in Bristol, he lived in Heraklion, Crete, from 1987 to 1991, working on the administrative side of SunMed which became Redwing Holidays and then part of Owners’ Abroad (now First Choice).
