I'll throw my hat into the ring as we've (unusually?) veered a bit off topic........
We moor at Brundall... we did moor at Wroxham but didn't particularly like the extra aggravation to get there (we visit the boat frequently).
We spend two fortnight periods a year (May and September) oop North and apart from the drag from Great Yarmouth to Acle we do enjoy the upper reaches of the rivers there. The villages/towns/rivers are very attractive but therein lies the rub... everyone else thinks so!
However, as we're well retired, we can go when we like and May/September are a compromise between the weather and number of visitors.
We haven't experienced life there in June, July and August for probably over 30 years but considering the problems we get with moorings when we do go then I doubt we ever will venture North again in those three months.
Conversely darn Sarf we do have long journeys watching, as Mark says, reed-banks and dragonflies. We choose to have an Alpha forward-drive 'cos Mary-Jane doesn't have to climb up and down stairs and we have grown accustomed to just looking for the wild-life that you can see from our restricted views. There's a lot to see out there as you trickle along with the tide at just above idle revs!
