Just so you know, any bags you carry will be searched as you go in. So if you can fit everything into one bag, part of your group can go on in, instead of taking a long time to get everyone searched. If you carry cameras or other electronics in cases, you have to open your case and show what is inside as you walk by. Other than that, you can have basic things like food etc. Naturally you can't carry weapons and there is no smoking on disney property. Those are really the only rules I can think of off the top of my head.
