I traveled from New York City to Disney World and back in 24 hours. It was exhausting, but I saved hundreds of dollars.

Since getting on rides was a big priority for me, I spent a little more on ensuring I could skip lines.

Disney World has changed a lot in the 11 years since I last visited. In 2013, I received a physical ticket to the parks and used FastPass to maximize rides. But FastPass has been a thing of the past since 2014, and visitors can instead buy a Lightning Lane Multi-Pass, which I decided to opt for.

After tax, my $232 park-hopper ticket was $247 (yes, that means the park ticket cost more than my airfare). But after adding the $24 Lightning Lane Multi-Pass in Hollywood Studios and the $20 Single Lane Pass for the TRON ride, the final cost was $291. Those prices aren’t stagnant, though — they go up and down depending on how busy the park is expected to be.

A park-hopper ticket lets you visit multiple parks in one day. A single park ticket would have been cheaper, but since I was there for just one day, I wanted to see as much of Disney as possible.

At first, I was pretty confused by the way the Lightning Lane passes work. Until recently, Disney used Genie+, an add-on service where you could purchase FastPass tickets to wait in a short line for rides. To secure them, you had to log onto the Disney World app at 7 a.m. the day of your visit and pray.

As of July 24, the parks use Lightning Lanes, which go live two weeks before your visit if you stay on Disney property, or three days prior to your visit for everyone else.

Either you can purchase a Multi-Pass for one park, which gets you time slots for one top-tier ride and two lower-tier rides, or you can purchase a single Lightning Lane for some of the most popular rides, like TRON, Guardians of the Galaxy: Cosmic Rewind, Tiana’s Bayou Adventure, or the Seven Dwarfs Mine Train.

If you purchase the Multi-Pass, you’re allowed to have three slots at once. Once your first slot has passed, you can check the app to add another ride.

I chose to apply this to Hollywood Studios since it had the most rides I wanted to try, and then I added the TRON Lightcycle ride in Magic Kingdom since that was my No. 1 ride in the whole park.

If this sounds overwhelming to you, you’re right! But once you get the hang of the app, it makes more sense.
