Pros
Travel, living in wonderful locations, the chance to live in a completely different culture and have a life that isn't possible in the UK even for a season.
Cons
Management are a bit cliquey in the country I was in. I had wonderful managers in my winter roles, but a specific manager in the summer was not honest with me until she realised that I had an intention of continuing to work for the company for a longer time, at which point she made clear she didn't like me and thought I couldn't do my job despite me having been there for a year and a half already. At this point the whole experience took a turn for the worse and the enjoyment disappeared. It is impossible to continue working in a country where you know very few people when management are making your life hell, although other managers were very supportive it was never in front of the manager in question so at to not disturb the clique.
