Greetings, Riyah!
Thanks for bringing this question to us. My son is also a huge fan so I know just how exciting movie release day can be! I've spent many hours listening to him as he tries to educate me on all the character variations and multiverse details. I still leave the conversation just a little confused but impressed by his attention to detail nevertheless.
While "Spider-Man: Across the Spider-Verse," which is scheduled to be released in June 2023, is sure to be an epic story it hasn't been officially confirmed as part of the Marvel Cinematic Universe. I know a number of fan theories are floating out there, many of which my own son would love to talk anyone's ear off about. However, I just reached out to a
Disney Cruise Line Cast Member who confirmed that it's not currently on the list of scheduled movies. They did advise reaching out closer to your sail date as entertainment is always subject to change.
There are still a number of ways you can make your son's birthday magical while sailing on
Disney Dream. Be sure to mention the
happy occasion in the "Special Requests" section under "My Reservations" so Cast Members are prepared to make your birthday boy feel extra special. You can also look into some of the
Onboard Gifts like room decor and treats available for purchase. One of my family's favorite ways to celebrate on Disney Dream is with something extra sweet from
Vanellope's Sweets & Treats. There's nothing better than a birthday sugar rush!
Your itinerary (which looks absolutely amazing by the way) is also one of Disney Cruise Line's 25th Anniversary sailings. These
Silver Anniversary at Sea itineraries feature special entertainment, culinary delights, and exclusive merchandise. You'll also get to see Captain Mickey and Captain Minnie in brand-new celebration looks! I think it's safe to say you're in for an absolutely magical 9-Night Mediterranean experience!
Don't hesitate to sail back and "sea" us again here at planDisney. We'd be happy to help answer any other questions.
Bon Voyage!
Amy
