Supermarket prices are similar to ours. Wine can be cheaper if you buy cheap brands. Beer is about the same price. Buy local produce and it will be cheaper than here for fruit and veg. Meat can be dear.

Driving is easy. There is a separate forum for driving in France, take a trawl through that.

Driving from a channel port to Paris is about 2 to 2.5 hours but Disney is on the far side so will take longer depending on route and time of day to negotiate Paris.

You can either go into the route periferique on the A1 or A16 and then come out on the A4 (to go towards Disney) or an alternative is the A1 to Charles de Gaulle airport then the A104 round the edge of the City to the A4.

Might I suggest that you use http://www.viamichelin.fr to help you with your route planning. It will also tell you where the toll booths (péages) are and how much you will need to pay. The first toll booth after leaving Calais is at St Omer, which has pay points on both sides of the vehicle for ease of those driving righthand drive cars. From then on, it'll be the front seat passenger who will do the paying.

Petrol is cheaper off the motorways, and supermarkets have the cheapest petrol of all.

A decent diesel will get you from the UK to Paris and back to the UK without needing to refill in France! However as Alsacienne says supermarkets have the cheapest fuel. Most are fill and then drive to the booth to pay. They will take Brit credit cards at the booths. However outside normal opening hours and on Sundays (and saints days) the pumps are on automatic and will only take French plastic!

I think that petrol and diesel are cheaper - just a bit - this side of the channel. The nearest filling station to Calais docks is at exit 2 - Calais Est - at the supermarket opposite a big lycée. If you are travelling outside working hours, it doesn't like UK cards ... but will take them at the petrol pay point.

Instead of Viamichelin I would recommend you try Mappy ( http://www3.mappy.com ) as a first timer they would find that the way it prints out with the Road signs as they are in France is a help

a Good diesel can get from London to Paris and back on a full tank so fuel shouldn't be a problem -- at 75 on the French Autoroutes I managed around 50mpg and 60mpg when I travelled at 70 obviously sans caravane

Some French 24 hour petrol stations at supermarkets do take UK bank cards but they are getting more common as France moves to the type2 chip and pin, but all French ATM's do work and yes ALL non Autoroute petrol stations are cheaper
http://www.carbeo.com/index.php?m=1&d=062 is a useful site for finding prices before you travel so you have an idea where the cheapest prices may be
