JoannaI count 8 relevant answers to your question, plus a link to another thread where this issue has already been covered in some depth.
As an experienced forum Administrator, I´m aware that threads can stray very slightly away from the original question and not return, and as I was conscious of other similar threads on this subect, I was just trying to make sure I got as much relevant detail as I could as the thread was straying away from the question I was asking.
SueOskar, do you make it plain on your form/T&C's that guests should have insurance to cover cancellations?
I don´t have any T & Cs as I don´t take bookings, my owners handling the bookings. I do give them advice though for their booking forms, hence the reason for the question - researching what other people stipulate as cancellation terms.
