If you have kids and they tend to want the flashy spinners in the evening-stop by wal-mart, the dollar store, or target and buy some much cheaper glow sticks and necklaces. Bring them to the parks with you, they don't take up much space and are light weight, and bring them out when it gets dark!
Here are some Great counter service locations that are favorites of mine and that offer big portions that can be split:
MK-Cosmic Rays
EPCOT-Sunshine Seasons
AK-Flametree BBQ
DHS-Pizza Planet
Also you don't have to order full meals-its cheaper and easier on the waistline and on waste period if you just want a burger and a drink,,,just get the burger and drink...don't get the meal just cause you think you're getting a deal,,cause often you aren't!
