Hi Amanda!
Thanks for bringing your question to planDisney. I'm thrilled to hear you'll be enjoying a fireworks dessert party during your February visit. I enjoyed the Post-Party a few years back and loved the sweet treats and beverage options included with the purchase, not to mention the reserved viewing area for the actual show!
I took a look at the
Hours & Events Calendar and see that
Happily Ever After is currently scheduled for 8 p.m. on February 5th, but I recommend confirming this again as your trip date nears, as timing may be subject to change. Your confirmation email should indicate all the details for your event, but in my experience, you'll check in at the podium near the entrance of Tomorrowland Terrace Restaurant.
The Magic Kingdom Fireworks Dessert Parties: Pre-Party landing page states guests should check in 90 min before showtime, which would match your 6:30 p.m. reservation. I'd plan to arrive as close to that time as possible so you have ample opportunity to get your wristband, be escorted to a table, and then sample all the delicious snacks and drinks. Cast Members will escort guests to the Plaza Garden viewing area before the show begins.
Keep in mind that guests who have purchased reservations for
Magic Kingdom Fireworks Dessert Parties: Post-Party or
Magic Kingdom Fireworks Dessert Parties: Seats & Sweets are advised to arrive 60 minutes before showtime. Be sure you've checked in before those guests start to arrive to reduce your wait and ensure you can enjoy the full value of your purchase.
I hope this helped, Amanda. If we can answer any additional questions please come right back to planDisney and let us know. Wishing you a magical visit!
Magic and memories,
Amy
