Haunted Mansion or Pirates
I am Small World fan. It's not too scary, it's not too intense, the theming is great, and it is a semi-classic. It is one of the 4 rides that Disney designed for the 1964-5 Worlds Fair in NYC, and while there have been updates, the spirit is exactly the same as when it debuted.It's a Small World
My first trip was also as an adult. For me, what made my first trip most magical was the nostalgia factor. My favorite movie as a girl was Little Mermaid, so I rode that first, and even though it is not one of the more "popular" rides it blew me away, and it's now tradition for me to ride it every trip. I also felt a lot of "wow" at Peter Pan--another childhood favorite of mine. 7DMT is super fun, but it doesn't have the same pull for me because I never watched snow white much as a kid because that witch scared me so much!
So I'd vote think back to what YOU love that is Disney and do that.
For the very very first ride ever at MK, I would recommend Peter Pan's Flight, it's simple, whimsical, magical and immersive in a very story book way. It's not the absolute best, but it puts your mind in Disney mode
Peter Pan because it's just quintessential Disney. My next votes would be Haunted Mansion or Pirates of the Caribbean.
Peter Pan's flight....it's always my first ride every time I go into Magic Kingdom.
My 19 year old son suggested Peter Pan. It is a classic and all Disney.
My suggestion is to get to MK early, stroll down Main Street, walk through shops, watch opening ceremonies. (It always makes me cry) and go to fantasy land. I would start out with 7DMT and Peter Pan, hop over to Its a small world, the carousel, Pooh, Dumbo and philharmagic but have FP+ for the 3 mountains (splash, thunder, and space) . Fit HM, pirates and Jungle cruise in during the day somewhere, and make sure to catch the parade at night. I know this is way more than just 1st ride advice (I got excited and carried away) this was an awesome question though. My first trip as an adult with 3 little kids in tow was Alien encounter (1999 and not there anymore) and had issues getting then DD6 to ride anything else for at least 48 hours because it was WAY too scary.
peter pan. go to MK an hour early before opening. Enjoy main Street, watch the wwelcome show and then high-tail it to Peter pan, through the queque. It really has amazing pre-show. And at that hour, the wait is not too long at all.
Haunted Mansion has always been my personal fave but if you plan to be at Magic Kingdom when they open, I would go to Peter Pan first as the lines get crazy.
Peter Pan, first thing at RD, so you can walk thru the stand-by queue.
Space Mountain or Big Thunder MountainAt 26 years old I’ll be going to DisneyWorld for the first time ever. Not considering wait times what attraction in the Magic Kingdom would you pick as your first ever Disney ride?
