Hi Hong!
It sounds like you are planning a visit to the "most magical place on Earth" and I'm happy to help you with this awesome question! The Walt Disney World Resort theme parks have so much magic for Guests to explore and I'm sure you are going to have a fantastic vacation.
Guests are welcome to bring outside food and drinks with them into the theme parks. Keep in mind that you cannot bring any glass containers or any alcohol into the theme parks. Also, your backpack or cooler cannot be any larger than 24" long x 15" wide x 18" high (61 cm x 38 cm x 46 cm). Finally, loose ice is not permitted into the theme parks, so I recommend that you use reusable ice packs to keep your food or drinks cold in your cooler. You can check out the
Walt Disney World Resort Park Rules for additional information. The Florida heat can be very intense, so bringing water and drinks with you into the theme parks is a great way to make sure you can stay hydrated. Plus, I always bring snacks with me when I'm traveling with my family so my little ones' little tummies don't get too hungry during our day!
I hope you're planning on taking advantage of the
FastPass+ System to make the most of your time in the theme parks. You can make three advanced FastPass+ reservations for each day of your admission ticket and when you redeem those reservations, you can enjoy
attractions and
Character Experiences through a special FastPass+ queue and bypass their Standby queue!
Let us know if you have additional questions as you continue planning. T-T-F-N, ta ta for now!
