The Pirate & Princess Party is a hard ticket event, which means it is separate from your regular park admission. It is themed around

and

with special character meet & greets, treasure areas and dance parties. Best of all are the special fireworks spectacular and the parades...MUCH better than then the usual!!
I went in February and had a BLAST!! I highly recommend it
