when i went end of august, it cost me about £450 some things were shared tho, E= euros ferry there euro back £65 (shared between 2) fuel based on an ep3 averaging 30-35mpg tops, just over 1000 miles, total cost £250 but split 3 ways laps around the ring are about E25 each hotel 4 nights B and B E180 food and drink all eating out is, for very good food E15-20 for a steak and a couple of beers, pizza is cheaper! we had a bbq one night for 10 of us, chipped in E5 each and had waaaay more food than we could eat! a 5L keg is £10 and they have a very good recycling service, you buy crates of bottled beer (20 pints i think for E12-15) then when you finish them u take the whole lot back and get about E3-4 off your next purchase so total based on 2 sharing its about £450-500 for 4 nights B and B with track time, ferry, fuel, food, drink etc! so if you were to camp out then you could save a good £90 id say, imo its a cheaper holiday than going on a clubbing holiday
