Tom, there is plenty of bank space but the best areas get crowded - it's 50 acres. Last year I got there late but still got in and had 9 or 10 fish.
You do need wellies or waders, by the way, as many areas are very shallow and you have to get in past the reeds.
Quite a few of the season ticket anglers pack up at lunchtime, so spots do become available. 8 or 8.30 would be better though
Or go next weekend and have plenty of space - pm me and I will send you my mobile, so if you do come, I can give you some idea where to fish and methods.
