Hi Raea!
Welcome to planDisney.
A first visit to Walt Disney World is so exciting, but I know it can also be a little overwhelming. I'm very happy to help with your question - let's work out the timings.
The
EPCOT nighttime spectacular -
Luminous The Symphony of Us - is showing each night during the week of your visit at 9.00 pm. The show lasts for around 17 minutes and takes place over World Showcase Lagoon. You will need to exit the park at the International Gateway, which is located between the France and United Kingdom pavilions. From that exit, it's around a 6-minute stroll to
Disney's Beach Club Resort. So to summarise, I'd allow 20 minutes for the show, and even if you wait awhile for the crowd to disperse and allow another 20 minutes for you to walk from your viewing spot to
Beaches & Cream Soda Shop, you'd still have an extra 20 minutes to spare for your 10.00 pm reservation. So, yes! 10.00 pm is probably a perfect time for you to enjoy something delicious at that restaurant. Dare I ask? Are you tackling the infamous Kitchen Sink?
Here is an EPCOT Guide Map so you can find your bearings around the park.It must be noted, however, that the park closes at 9.00pm (obviously allowing everyone who is already in the park to stay for the fireworks). So if you were intending to walk back through the park from International Gateway to the front entrance, where the parking lot and bus stops are located, after your dining reservation finishes (around 11.00 pm?) you may not be permitted to do so. In preparation for this, I would start my day by taking Disney transport to EPCOT from my Disney Resort hotel, and then use a rideshare from Disney Beach Club Resort to return to my hotel. I use Lyft - download the app to your phone - it's usually fairly inexpensive (depending on where your hotel is located), and would be a convenient and easy way to return to your hotel that late in the day.
Please come back and visit us if you have any further questions, and you can
send me a direct question if you wish. We will be happy to help you plan your magical vacation to Walt Disney World!
