Probably the best place to save money is in your food budget. We do the same as previous posters, eat breakfast in room. Cereal is always my family's favorite. You can keep the cooler for milk, or even at Pop you can rent a fridge for the room. We've done that in the past, but you can save the money and just keep a cooler. Your call on the convenience factor. We've taken other breakfast stuff as well. Also, carry snack or two in your back pack. It'll hold off hunger in a pinch. We like to eat one sit-down meal a day. Usually a late-ish lunch (1:00 or so) then we either eat counter service or munch during the parades, around the pool, etc.
Next best place to save is souvenir $. It's easy to get sucked into the "I want the world" mentality when you're there. Set a solid budget before you go as to what you're willing to spend. We always give our kids x amount of dollars and it's their choice how to spend it. We buy all the meals and some snacks, but not all the candy and junk. That's their call. Example: We might buy a round of ice cream for everyone or popcorn, but only if we're all going to enjoy together. If it's something just one of our kids want, then they have to decide if they want to burn some of their money on it. (Amazing, by the way, how discriminating they become when it comes from their wallet)
Also, with budget. We have taken many trips to the world. Some may disagree, but we have found it easiest to stick to the budget with cash. We bring what we're willing to spend and when it's gone, we're done! We carry a certain amount each day. Again, amazing how discriminating WE become when we see the cash in the wallet and see it disappear!
Hope some of this helps! The main thing is to have FUN!
