Hey there, Mark!
A springtime visit to the Disneyland Resort sounds like a blast with you and your crew of fellow Mousketeers. You'll get to enjoy
Get Your Ears On – A Mickey and Minnie Celebration including Mickey's Mix Magic, the "World's Biggest Mouse Party." You'll also be able to catch the last couple days of the
2019 Disney California Adventure Food & Wine Festival, continuing through April 23. You'll want to download the
Disneyland app to keep up with these events and more during your visit. It's also a great tool to use for such things as checking attraction wait times and placing
Mobile Food and Beverage orders.
My family loves to take in snacks and drinks to stay energized and hydrated while enjoying the Disneyland Resort. I'll usually toss these items into a backpack, and off we go! You are more than welcome to take in as many coolers as you can reasonably carry in your group.
Disneyland Resort Park Rules do have a few guidelines about coolers. The main thing is that coolers may not be larger than 24" long x 15" wide x 18" high (61cm x 38cm x 46cm). Alcohol, glass containers, loose ice, and dry ice are also prohibited. Re-usable ice packs are recommended for keeping things cool.
Lockers are available for rent if you need a place to stow your gear.
I hope you have a magical time, Mark!
