what things would you recommend for things to do in and around hopton on sea i will be there mid may for a week
Well, apart from the myriad delights of Great Yarmouth and Lowestoft, both easily accesible by bus, you might want to head down the coast to the pretty seaside town of Southwold, or across to the City of Norwich.
You might also be interested in these historical pictures of Hopton-on-Sea:
You don't say whether you have transport but lets assume you have and that you're adults only.
Further afield and a very long day, but worth it if you haven't been before is Sandringham, where the Queen spends Christmas.
Beccles is nice, Southwold is a must and Somerleyton Hall is just up the road, 10 minutes away. http://www.somerleyton.co.uk/
Forgot to say that if you're staying at Potters leave a day in your week to spend on site as there's always lots to do there.
It depends what you are looking for. If you like funfares, amusement arcades and tacky touristy shops, Great Yarmouth would be good, and Southwold and Sandrigham a waste of time.In any event, if you are coming from Sheffield, you will most likely use the A47. This road passes within a few miles of Sandrigham so if you really want to visit, do it on the way to Hopton or on the way back. Lowestoft is quite pleasant with good beaches, and Gorleston has some pleasant cliff top walks. If you want a day on the broads, Stalham or Wayford Bridge might suit you better than Wroxham, being in a very much quieter part of the broads, or Oulton Broad, which is very much closer to Hopton.
