my two were six and 12 the first time I took them by myself to WDW. I made them customized business cards with their picture, their name, the resort phone number, and my cell phone number to put in their pocket. I made sure they knew to only approach Disney Cast Members for assistance. I also think it is a great idea to take a picture of them in their outfits for the day in the morning, that is very helpful. We have never had any problem, just the two children and I, and now that the oldest one is 16, I actually let him go off on his own to MK, MGM, and Downtown Disney, while his little sister and I re-visited AK. No problem at all, he met us back at our room exactly when we had arranged to.
Have a great trip!
