I agree with this...I haven't been to Disney yet but I have walkie talkies and they are the 10 mile ones...sometimes my 111/2 year old son doesn't like to run an errand with me so if it is just up the road I will take one with me and unfortunately the farther away you get the worse the reception...I didn't like this at all...lots of static and interferance...had to repeat yourself alot of times too. I just put my cell # into the memory on my home phone and now if he needs me he can call my cell. He knows the rules of not answering the door...AT ALL...and when he answers the phone, if it isn't me, daddy or is sister, he is to hang up immediately. I know 11 is young to let home alone even for a few minutes but I think you have to start getting them responsible at some age. My daughter took the babysitting course at this age and was babysitting at age 12, so he isn't that far ahead of giving kids alittle leadway. He is a good kid and while I am gone he just watches TV, plays on the computer, or plays Nintendo. I'm gone 30 mins tops!
Anyways...back to the walkie talkies, I am still bringing them with me for the hotel...never know what I might want them for...better to bring them then leave them behind and want them.
Just my 2 cents here!
