Via Michelin will help you with all your European travel planning; whether you want to find a restaurant in Paris, a road map of Zurich or a hotel in Milan - it's all there ready and waiting. This is the online version of the famous Red Guides but unlike the Red Guides, where the road maps are extremely limited (the town maps are excellent) here you just key in your starting point and your destination and it'll tell you exactly how to get there, no matter how many borders you're crossing. It'll give you hotels and restaurants on the way and even tell you how much the tolls are going to be.

I don't know about you, but every time I make out the holiday packing list I leave something off. Well now there's no excuse.

You do sometimes have to pay a small charge for a year's subscription although they have free offer periods as well but I think you'll find it worth it.
