The broads by its nature are a series of rivers, lakes, broads and marshland. The are very few places to build so called entertainment for people. Lack of mooring at Yarmouth,Norwich, Oulton Broad and most Riverside pubs is a subject the broads authority needs to address first.
What sort of things are people asking for. As the broads tend to be empty during the cold months most entertainment venues suffer a few lean month's so it's most unlikely things will be built in the middle of nowhere next to a river.
People who hire boats that want more do not see the downside of the entertainment industry. They would be better off going to a holiday camp thus leaving the broads to those that appreciate the peace and tranquility.
