Lexy, we have four walkie-talkies. They work great. Agree ahead of time what channel you're going to be on. If there is interference, just move to another channel. Be aware that if you're traveling during a congested time, with many children onboard, you are more likely to encounter "clogged channels". We've spoken many times to strangers on the ship. All in all it's a great way to keep track of your children's whereabouts on the ship. I strongly recommend them.
