DH and I are going to Disney for a long, much needed Disney vacation. My in-laws are meeting us there for a few days of our trip and we are planning events/meals together. But if we happen to be at the same park and want to separate and meet up somewhere later in the day, we believe there are walkie-talkies you can rent at the parks. If this is correct, how much per day are they? Or is it worth it to just purchase them and if so, where and how much? Thanks for your help!!!
