Welcome to planDisney, Lacey!
You are correct that Halloween (October 31) is a Tier 5 day. To
purchase a theme park ticket for this day, you will simply select that day from the calendar when you purchase online and you will automatically pay the Tier 5 price and have the correct ticket for that day. Then, you will select the park you want to visit that day and that will be your
theme park reservation. After checking out and completing your purchase, you will be all set to go!
You definitely won't want to miss taking a ride on Haunted Mansion Holiday or seeing Mickey and his pals in their Halloween costumes. They usually hang out around the Disneyland Railroad Main Street, U.S.A. station. You will also want to cap off your night with the Halloween Screams nighttime spectacular which is
currently scheduled for 9:00 p.m. Also, this will likely be a very a popular day to visit the parks, so you might want to
make a dining reservation for dinner or plan on using the Disneyland app to mobile order any meals or snacks.
I hope you have a ghoulishly good time at the Happiest Place on Earth!
