T.F.
We didn't use them for vacation but we have used them at our house.
We have some Motorola ones that are great. We used them as a novelty before we all had cell phones. The range was good...I am about a mile from the community pool. Daughter would walk there or out on the bike trails and stay in touch.
Great idea. But since daughter got her cell, the walkie talkies are in the cabinet and we text or call all the time. Even from upstairs to downstairs, lol.
