Another contributor to this site lives in Cornwall and has just accepted a place on the Exeter course. All the courses have placements, which are often geographically distal from the university. In Exeter's case (I can't speak for Plymouth) there are various placement locations (N Devon, S Devon, Exeter, North Somerset, E Dorset, W Dorset). If offered an interview you are asked to rank the placements according to your preference. If you are offered a place, they try to take account of your preferences and personal circumstances. Naturally, some will end up disappointed though. Also, if you are offered a place from the reserve, you will have to accept whatever placement is offered.
There are five Exeter placements: two in Year 1 (6 months each, I think), two in Year 2 (6 months each, I think) and one in Year 3. Read the Clearing House page for more details of the Exeter course philosophy. Briefly, it's quite CBT-orientated, though they also like psychodynamic (CAT) and systemic. To my impression, Exeter is relatively research focused. One of the three interviews is dedicated to research and is rigorous.
As to whether you have enough experience, who knows! It looks like you have lots of experience though.
