Which internship?

I have to do an internship for school. I dont know if I should stick to the one I did last summer which was a lot of fun with hot benefits or should I try something different. I dont want to be stuck with a boring place for the summer where I hate the people and hate the work. should I stay with the relaible or go for what could be a mistake?

Because you are still young I would go for the internship that is different and new. You want to have as much experience available to you and by go to a different company you can get just that. By interning at different companies you are able to compare and contrast the qualities within the companies and are able to see what you like and dislike.
