Ray, I have a motorola FR60 with the subchannels and I always take them to WDW and they work wonderfully, the distance range is 2 miles so as long as we are in the same park we can reach each other , dh was in our hotel room last year at the contemporary and he could talk to us in Fantasyland , I really love taking those things. I also do have my prepaid cell phone which I could use too but I don't think I would give my number out to many people..LOL.
I don't know if this would actually be a good idea but it's a thought!
