Mid-April thru (IIRC) Mid-June the weekends at MK are booked up with High School seniors from all over Florida celebrating graduation. The exception is Memorial Day Weekend. These events have been going on since at least the 80's. They begin at 8pm and end at 2am; featuring popular bands, special fireworks, etc. You can easily hear the music at FtW across Bay Lake. It's a hoot to watch all these kids disembark from the busses at the TTC. Up until I think it was two years ago, these kids had to be DRESSED, like they were going to prom or something. Girls in heels & dresses, guys in dress shirts/slacks & nice shoes. It was something to see. Now, I think they are allowed to dress casually. (Which is a good thing IMHO!) If you are in 100 thru 500 loops (and 700), you will hear the music. Grab your favorite beverage, sit back, relax & enjoy!!
