Hiya Lori!
Welcome to planDisney! Thanks for visiting us today, and how terrific that you get to combine attending a convention with a little spark of magic in the evening. Woo hoo!
The benefit of
Extended Evening Hours applies to all Deluxe Disney Resorts, Disney Deluxe Villa Resorts and a few other select hotels. I'm happy to confirm that the Walt Disney World Dolphin Hotel is one of the "select hotels", and is included in this awesome perk. So, yes!! Because this benefit applies to all registered Guests at a qualifying resort... as a Guest at the Dolphin, you'll qualify to take advantage of the Extended Evening hours at Magic Kingdom.
You've likely already verified this already, but you can double check the
Park Operating Calendar to see which dates Magic Kingdom is offering Extended Evening Hours. What wonderful timing that this aligns with your evening ticket and plan to visit the park... that's my kind of happily ever after!
Be prepared by having your resort reservation and theme park ticket linked inside the
My Disney Experience app, as you'll need this in order to access attractions during those bonus hours.
You can check out this
list of attractions that will be open late, for planning purposes. Extended hours are amazing, with lower crowds and shorter lines... it feels like an extra sprinkle of pixie-dust! If you have any "must-do's" that you don't see on this list, make sure to swing by those before the standard park closing time for the evening.
Have an absolute blast at the Most Magical Place on Earth, Lori!! Please visit us any time at planDisney with your Disney vacation questions.
See ya' real soon!
Tami
