Can anyone help? We are off in September for first ever trip. Going as a group of 14. My question is with regards keeping in touch with each other round the park. My thinking was rather than paying silly mobile phone prices all the time. Take a set of walkie talkies of some sort. We can then keep find out each other wear about with out any phone charges. Has anyone ever done this? Is reception any good? Are we OK to put these in the suitcases. Dont want them to think we are carry a suspect package.
