Hi, Eduardo!
Fantasmic! is a wonderful way to end your day at Hollywood Studios. This is a very popular show, so make sure to be in line 1 hour prior to showtime.
I do not know your travel dates, so you will want to click
HERE for the June calendar for Hollywood Studios. When you are on the calendar page, click on the DATE you will be at the park, and that day's schedule of events will pop up, including park hours, parade times, and Fantasmic! schedule.
If you have a difficult time with this, write back with your exact travel dates and we can look those up for you. Have a wonderful and MAGICAL Walt Disney World vacation.
