No...the fireworks used to take place at the lagoon in the Studios but since Harry Potter was under construction, they cut it out. Hopefully fireworks will return this summer. BTW...fireworks were only done during periods when the parks closed late like holiday periods and during the summer.
we where there the month of July metro, and they had them every night. Not as good as before the construction at HP ,but they where ok.
definetly not worth staying for that night to see them
