It is scattered throughout the month of October. It should be good for the 11 & 13 year olds... but some of the haunted houses may be too much for the 7 year old.
It consists of:
5 haunted houses
parade
Bill & Ted show
another show that varies year to year(last year was a magician)
street performers and scaractures
a Kong street walk-through(but do to Kong possibly closing, this may not happen)
some rides are open
I thought it was fun and worth the price, just make sure you go early in the month because it can get WAY too crowded towards Halloween.
