Hey there, hi there, Kosuke! Welcome to planDisney. You have brought us a great question about guided tours at Disneyland Resort!
I am excited to hear that you are thinking about experiencing a guided tour at Disneyland Resort. There are currently a few options available and they can be a really special way to experience and learn more about Disneyland. I took a look at the current guided tour offerings and it looks like all of them have a 24-hour cancellation policy. This means you can cancel up to 24 hours in advance to receive your refund. If you do not cancel before the 24-hour time frame or simply don't show up, you will be charged the full amount. Be sure to check out the
guided tour page you are looking into for more details.
I have been looking into
Disney's Happiest Haunts Guided Tour because Halloween time in the parks is one of my favorites. I love that this tour also gets you an expedited ride on Pirates of the Caribbean, a photo op with Hitchhiking Ghosts, and a reserved viewing area for Halloween Screams.
Kosuke, thanks so much for stopping by. I hope you figure out a plan and if a guided tour is a good fit for you during your park visit.
