9. Water Bottles
Unlike TSA, Disney World security will allow you past the checkpoints with a full bottle of water, so be sure to bring your own bottle to avoid having go pay over $3 for a fresh one. There are plenty of water fountains around the park, so don’t be too quick to recycle your bottle and grab a refill when you spot one. Many Disney trips have taken a turn for the worse when someone gets dehydrated, so be sure to keep drinking your water!
