One of the biggest challenges is that you never really know what to expect and need to be prepared for every eventuality. But that is also one of the best parts of the job! I have gained so much experience; in running a team, in planning and organisation and learning to work under pressure. The experience you gain during one summer is unique and I would find it hard to believe that you could achieve so much in any other job. Go for it!
