Hi James, If you,look further down the page you will see answers to a similar question. We went to Lake Garda last year and had a brilliant time. We live in Portsmouth but went Dover Calais due to price difference,we went on afternoon ferry travelled down to Reims stayed overnight at municipal de fismes.We then travelled through France and did a two night stop in the Alps(about a 7 hour
journey with stops) We stayed at Le coin Tranquille,which is a lovely site with a fantastic restaurant and a nearby Hypermarket for supplies! We then travelled through the Frejus tunnel to Camping Fornella again about 7hours. This journey is expensive on tolls,however it was a quick and easy journey and its difficult to get lost on Motorways!
The campsite was lovely and you could walk to the lake at the bottom of the Site, When we arrived the site was packed and was a bit daunting after the big pitches in France,we had a pitch near the pool, which by the way is lovely for young children, our pitch looked tiny! however some lovely Dutch people helped us site it and it wasn't as bad as it looked. We could fit the car on the pitch but there were parking areas near by. We intended to drive round the whole lake visiting all the lovely villages,but we ran out of time. Nearby is a theme park called Garda Land which we all really enjoyed.And as Evans of Sprott advised us "you really must go to Verona" and you really must,allow a whole day and Evening. I also had the 'pleasure'of visiting the Ferrari factory!
I know most people do not follow this route because of the tolls but it really is very easy with a caravan.We booked through the caravan club which really seems to be the best price for the school holidays. If going out of season you could try camping cheques,which Valerie on this forum knows about.
Hope this helps
