Vodafone Eurotraveller - No Thanks!

Those nice people at Vodafone have just offered me their Eurotraveller product at £3 per day for every day I use my mobile in Europe (I would then be charged at my normal charge rates). Now I go to Europe for a holiday - i.e. to get away from things. And that means minimal 'phone usage - probably less than 5 minutes on any day that I actually use the 'phone. So £3 for the marginal second seems like rather a lot. No thanks, Vodafone!
