I did modball a few years ago, and thought it was quite badly organised. Hotels werent upto what we were told, lack of propper parking, parties and hotels miles apart, and just generally too far between stops. Certainty wouldnt go on it again, although i got to meet Lucy Pinder.....
Check out the Rico Rally, hear lots of good things about that. Police were never an issue to us other than on the Swiss border, and they were just keen to check everything!
