Hi! Bought two way radios yesterday - thought good idea if family decides to split up in parks - but reading instructions they work only in europe! ah Anyone used them out there? Its got 8 km distance and 300 channels if that makes a difference. Thanks for your help!! 

box (along with the toastie machine and footspa!). They're not as bad in the parks due to the lack of brick built buildings, and the advantage you will have, being British there will be far less people using the wavelength.
and if switched off for shows/rides etc .. you recieve your message when you switch back on
