Hello,
Just a little warning concerning walkie talkies......
Different Countries use different frequencies and channels.
The proper type of walkie talkies for France + all of EU is called PMR 446.
France + EU = PMR446 = 446Mhz (8 channels)
USA + Canada = FRS + GMRS = 462,467Mhz (22 channels)
USA = MURS = 154Mhz (4 more channels)
Australia UHF CB = 477Mhz (40 channels)
There is no problem with anyone using the PMR446 in France including Americans and Canadians, you just have to buy a pair in Europe, and only use them in Europe. If you already live in the UK or Europe, you probably already have the correct PMR446.
The PMR446, AUS UHF, FRS, and GMRS are all UHF and have a slightly smaller range than the MURS which is VHF and over 1 watt in power. Generally, FRS PMR can cover only 1/2 of a disney park in range. Only the MURS or even stronger commercial radios can cover an entire park (but not certified in Europe for personal use)
If you want to be a bit crazy, you can have absolute privacy by using the FRS/GMRS in France, and the PMR in USA, since no one else is using those channels. Don't get caught doing this. Imagine if the 462Mhz band is the police band in France for example. You would be transmitting all over the police network while chatting with your family on the walkies.
Play it safe and only use PMR446 in Paris
Disneyland. You can find them on european and UK ebay.
