I've actually spent spring break in Key West as a student many years ago and can echo Phil's comments if you are having a family holiday.
I was one of the "revellers" and had a great time[msnembarrased] but would avoid it now with my family.

We have stayed at our villa in Rotonda twice during march and have had no problems round that area.Not a plug as we are already booked for the whole of March next year but it may be worth looking at somew of the Gulf villas on the link above.
