I think your budget will be fine. Camping: 11E a night. We paid 33E for two nights last Spetember, but I think we actually paid for a night more then we needed. Unless Saturday nights are more expensive. Anyone speak German? 'Ring: 19E singles, reductions on multilap tickets; which can be shared or sold onto 'Ring whores ;-) so say 15E a lap + 4l of petrol! Last Easter, IIRC, people only did 4 laps. Food: From memory, 15-20E for a resturant meal with beers. Lunchtime snack 5-10E or there are two Lidls locally which should be open on Saturday. Extra Beer: Who long is a piece of string :
