Hi Ratan,
Welcome to planDisney! I love to see that you are already planning some great ways to stick to your budget while traveling to Walt Disney World. While the food there is excellent and worth a splurge or two, bringing your snacks can be a great way to save money while traveling.
The best option for finding a place within the theme parks that can provide hot water is by looking in the
My Disney Experience app for a
quick-service dining location that serves warm drinks like hot chocolate or tea. These locations will likely have access to a hot water source and will be willing to help you out. Most quick-service dining locations will fall into this category except places like food carts or booths that don't have access to hot water. We did this frequently when we visited with an infant to warm bottles and most of these quick-service locations were accommodating. Keep in mind that this is always subject to change and is not something that is guaranteed.
Remember that when you enter the parks, especially if you are traveling with a lot of snacks and gear for the day, your bag can not be larger than 24" long x 15" wide x 18" high (61 cm x 38 cm x 46 cm). You also can not use loose or dry ice in any of your bags to keep food items cooled throughout the day. If you need to keep items cool, re-usable ice packs are typically the best option.
I would recommend splurging for at least one table-service dining experience while you are at Disney World because they have some truly amazing food options. My favorite place for a meal at Magic Kingdom is
Jungle Navigation Co. LTD Skipper Canteen. The food is unique, the atmosphere is fun, and it is a great place to sit for a bit and relax on a busy day!
Happy Planning,
Jenna
