I bought a Migo for my daughter for our first trip to Disney w/o DH. It was a phone very similar to Firefly through Verizon. Since we each already had a Verizon plan, it was easy to put both accounts together, add DD and it was only $10 more a month. Problem is, it too is annoying to program since you can only have 4 numbers programmed in at a time, plus 911. However, I felt safe knowing she had a phone and if we were separated, I told her to immediately find a CM, then call me. I didn't want her wandering around, obviously alone, trying to find me. I felt better knowing she'd be accompanied by a CM while waiting for me to get to her. It also made her feel like she had more control, should we get separated.
