Hi Ann! I can tell you've done your Disney research -- you're so smart to be planning your vacation in advance and scheduling your park visits around shows you want to see! You can find the schedule for Fantasmic, the stunning show at Hollywood Studios, on the
park calendar. Just change the month in the upper right corner to the month of your trip, and then click the dates of your visit on the calendar to see a pop-up list of events scheduled for that day in the park, including Fantasmic. The schedule is currently posted through July; August should be online in the next few weeks. I checked your July dates, and Fantasmic is scheduled for 9 p.m. on both July 30 and July 31.
Since you're planning to have dinner at Hollywood Studios and see Fantasmic, you might want to consider booking a
Fantasmic Dining Package. With the package, when you eat at Hollywood & Vine, Mama Melrose's, or The Hollywood Brown Derby, you receive a voucher for reserved seating at Fantasmic. The VIP seats aren't the best in the house, but they do save you from lining up over an hour before the show.
I hope your summer trip is magical! Come visit us again at the Moms Panel if we can help!
