Welcome to planDisney, Gilda.
I'm so glad that you stopped by with your question.
Magic Kingdom Park is my favorite park in Walt Disney World. From the iconic Cinderella Castle to the nostalgic Main Street, U.S.A, it has everything you want in a theme park. Some of my favorite rides are in Magic Kingdom Park too. I always face a dilemma when I visit; which attraction am I going to ride first? Shall I make a "dash for Splash" (i.e. Splash Mountain") or join the "race for Space" (i.e. Space Mountain)? Or what about the Jungle Cruise or Seven Dwarfs Mine Train? As Ursula once said, "Life's full of tough choices, isn't it?"
Here's the thing, Gilda: it all depends on you. I can give you my personal opinion. But everyone will have their own opinion when it comes to this question.
If I were you, I would get to the park as early as possible. If you're staying at a Disney Resorts Collection hotel, take advantage of the Early Theme Park entry. I would head straight to....

Jungle Cruise. Although this isn't my absolute favorite attraction in the park, it's a classic! It's so much fun and I think it's the perfect way to kickstart your day. Wait times for this ride are usually very long. Therefore, if you can get there before the crowds get busy, you're in for a treat. You can then make your way to Pirates of the Caribbean, Splash Mountain, and Big Thunder Mountain Railroad. What a morning that will be!
If I were you, I would also purchase
Disney Genie+ and try to book Lightning Lane entrances to minimize your wait times. Try to get one for rides like Peter Pan's Flight, Splash Mountain, Big Thunder Mountain Railroad, and Haunted Mansion, since they tend to have longer wait times.
I would also consider purchasing Individual Lightning Lane entrances for
Seven Dwarfs Mine Train and
Space Mountain.
That way, you can maximize your time in the park and get on as many attractions as possible.
I hope that's helpful, Gilda. Have a magical trip.
Mike
