We were away 4 nights in total. Not 100% on the cost yet - the diving and the accomodation in Aitrang was pretty good value. 2 nights in hotels, petrol, beer, food & so on pushed up the cost somewhat. Curiously the most expensive night was drinking in Belgium - hotel beer prices I suspect!
All round a top trip, & well worth doing.
Our trip went something like this:
Day 1: Drive Portsmouth > Namur, Belgium.
Evening 1: Beers in Belgium
Day 2: Drive Namur > Aitrang, Germany
Spent 2 days in Aitrang doing the diving. Lots of fun all round!!
