Hello Deana,
Welcome to planDisney, and thank you for bringing us this wonderful question today! My little heart skipped a beat just thinking about you getting to see two nighttime spectaculars coming up so soon! What a fun plan, and excellent choice of parks. Here's what I found out from the Park Operations Calendar for your dates.
On
March 30 at EPCOT, the fireworks show will begin at 9:00 PM. This coincides with closing time at EPCOT for the evening, and couldn't be a more magical way to end the day.
Luminous The Symphony of Us is incredible, and can be seen from lots of locations around the World Showcase Lagoon. If you can see the sky (no obstructions like trees or lampposts) and water from your spot, you'll get a nice view of the show!
On
March 31 at Hollywood Studios, Fantasmic will begin at 8:30 PM. This is a very popular show, so you will definitely want to arrive early in order to get seats. One option to guarantee an excellent spot is to book at
Fantasmic! Dining Package, which for a fixed price allows you to dine at a participating restaurant inside the park during the day, and then return later in the evening and get to watch Fantasmic from a VIP seating area! I do see some availability left for your dates, so consider reserving that soon if you are interested.
You're going to have such a magical time, Deana! Enjoy every moment, and
please stop by planDisney any time if I can help with anything else.
See ya' real soon!
Tami
