My wife and I will be travelling from Sydney to Paris in September this year with another couple. We plan to drive to the south of France, into Northern Italy, up through Switzerland and Germany then back to Paris. The trip will take 5 weeks and we have leased two Peugeot 308 sedans for the journey and we'll be following each other around.
However, one problem we haven't found a solution to is the matter of verbal communication between cars while on the road. We don't want to have to stop and talk. We want to be able to communicate freely and at will as we drive along.
We thought about buying walkie talkies in Sydney and taking them with us but they have a limited range and we could be separated by several Kms. We are also unsure about the frequencies used in Europe and their legality. Another option is a 'Travel Pack' from our local Optus Telco which offers unlimited text and talk on our mobiles, but at AUD$10 per day x 35 days = AUD$350, which is getting expensive. Unfortunately that may be our only option unless someone has another cost effective, practical solution.
Has anyone done a 2 car trip like this before in Europe? Your experiences and thoughts on the most cost effective and practical communication devices would be most welcomed.
