Valeria,
You're going to LOVE WDW! I checked the online calendar for July 24th since this is the day you would like to visit DHS. Unfortunately, Fantasmic is not scheduled for that evening. I don't know if you have other dates that you could possibly visit DHS or not. If you'd like to let me know, I'd be happy to check the calendar for other dates.
You can check the online calendar for performances of Fantasmic by clicking
here. To change the month, click on the drop down list next to the
View Month tab. Click on a specific date to see if & what times Fantasmic will be performed for that day. Schedules are always subject to change so be sure to pick up a Times Guide as you enter the parks to confirm the schedules.
If you decide to visit DHS on another date when Fantasmic is being held, keep in mind that guests begin lining up at least 90 minutes prior to the start of Fantasmic. To reduce your waiting time, you could check on availability for the Fantasmic Dining Package. On those nights that Fantasmic is held, the dining package includes dining at one of 3 awesome restaurants at DHS & seats within a reserved section of the Fantasmic theater. Two of the restaurants now offer lunch or dinner as part of the dining package:
* The Hollywood Brown Derby (lunch or dinner)
* Mama Melrose's Ristorante Italiano (lunch or dinner)
* Hollywood & Vine (dinner only)
The Fantasmic! Dining Package is available on all days when Fantasmic is scheduled. On days when there is more than one performance of Fantasmic scheduled, the Dining Package is only available for the first show. Reservations can be made by calling 407-WDW-DINE up to 180 days in advance.
I'll keep my fingers crossed that it works out for you to see Fantasmic - it is a awesome show!
