I live in the area, there are a lot of people doing it and it can be very busy in some areas during the peak season. Depending on where you go there are things to do but it kind of depends what you want? Bright lights and nightlife are not an option
There is Fairhaven Water Garden, St. Bennet's Abbey, Horsey Wind pump, Strumpshaw Fen, various nature reserves etc. but I suspect you'll mainly be pottering about and relaxing.
You'll find a fair number of pubs near moorings and moorings near pubs. I'm afraid a lot of the pubs on the water, while they're seldom very expensive the food can be very disappointing. You may also find the moorings are full up or loud into the evening. Same goes for the 24hr moorings at the busier locations, they're often packed out by mid afternoon which leaves people motoring on to another less interesting location or dropping anchor in the broad with no way to get into land.
The good food pubs are busy for lunch and dinner on the weekend so worth booking ahead.
Coltishall has a good selection of decent places to eat (Rising Sun, Kings Head, Recruiting Sergeant, Norfolk Meade)
Wroxham is the largest town you're likely to come across unless you loop down around Gt. Yarmouth and back up the Bure to Norwich. My kid goes to school there and there's not a huge amount to do around there bar the steam railway that takes you to Alysham. I'd recommend the Smokehouse at the Station and there's a large Supermarket (Roy's of Wroxham) that is walkable from the water.
Woodforde's Brewery /Fur and Feather pub near Salhouse Broad are worth a visit if you like beer
The Ship Inn, South Walsham is excellent and The White Horse in Upton is decent.
If you want to visit Norwich it is possible to moor right in the city centre quite near the Cathedral for an overnight fee. It's probably OK but you are at the bottom of the main drinking drag strip, The Prince of Wales Road so I'd avoid Friday and Saturday night.
Not sure about Yarmouth but it has a reputation of being pretty rough around the edges these days. Check if your hire boat is allowed to go all that way though, the day boats from Acle are not allowed to head toward Gt. Yarmouth.
In general the River Yare looks to be a lot quieter with more private boats than rentals.
If you're not convinced about staying on the boat there is plentiful holiday accommodation to rent and it's a good area for cycling and easy to drive about.
You could always rent a day boat in a couple of locations and benefit from mains water and electricity

Of course being local it's never occurred to me to rent a boat for a holiday, we get day boats. The smaller ones are OK but can be a pig to handle, ironically when we got a full size cruiser on a "picnic day cruise" it was much easier to pilot. The electric ones from Potter Heigham are good, as a chugging diesel does tend to disrupt the tranquillity a bit.
