For this year the cost of caravanning for us is quite high but that is because we have come back to it after a 20+ year gap. But when I discount the price of the caravan and all the bits needed,hitch lock ,wheel clamp, bedding, gas bottles ect,ect, I find that even with the cost of storage and insurance and stopping only at CC sites it is a hell of a lot cheaper than staying B&B and a damn sight more convenient. My wife and I reccon to get a minimum of 2 nights for the price of one B&B, thats allowing for the extra fuel used. Infact it works out cheaper than that as we usualy make our own evening meals as opposed to eating out every night. I haven't had to get a bigger car as I drove a large 4x4 anyway and find the extra mpg when towing about the same as driving around town. Infact it was the fact that I owned the 4x4 made me think of getting a caravan again as with my health flying to the sun for 2 weeks is not reccomended.
Next year after we've got used to caravanning I might concider driving to the sun for a few weeks.
