9. Bottled Water
As long as your water is not in glass containers, you can bring as many as you’d like into the Magic Kingdom. For most of the year, Florida’s weather is mild to hot, so bottled water is almost a necessity. At most quick service restaurants, cups of water are free, but having those water bottles in your backpack will be much more accessible, and there are plenty of water fountains around the Magic Kingdom where you can refill your bottles.
