I have stayed at Hunstanton a few times in the last few years.
Hunstanton is really 3 places in one. Here is a map to show what I mean:

"Old Hunstanton" (in the North) was the original village and is full of old buildings, a lovely church, duck pond etc, and is right next to the beach. But it is VERY quiet and very little to do there.
Then in Victorian times a railway arrived at Hunstanton at a rich man in the area built some lovely houses, a pub, town hall etc. I suppose this could be considered the Northern part of the main town. Many of these old houses are now B&Bs and we stayed in one of them a few times and it was lovely.
Then the railway closed down (it came in from the South) and this became a caravan site, fun fair etc, and is a bit tacky.
If you are staying on Old Hunstanton, or the Northern part of Hunstanton town, then that will be fine, if it is round then Southern part of Hunstanton town then maybe avoid.
I actually like Hunstanton a lot, Lovely beach and setting, nice cliff and cliff walk, fair amount to do, and inland from Hunstanton is really nice.
Also great sunsets as the town actually faces WEST (even though it is on the East coast) and the sun sets over the Wash so sunsets look great from Hunstanton.
