Brighton is very cool and lots to see and do, especially if the weather is nice. Lots of really fab small boutique shops, great funky jewelery places in "the Lanes", good seafood restaurants, lots of diverse restaurant choices. Great little bed and breakfast the "New Steine hotel" at St James sq. Each room has themed decoration, not the tacky theme kind very classy and very friendly unobtrusive guys who run it.
Closer to Wiltshire - Lulworth Cove - a gorgeous horseshoe bay and a fabulous walk to Durdle door- definitely wear your comfy walking shoes. I would recommend the Castle Inn if you are staying overnight especially if you can get one of the cottages which adjoins the Inn. Great food in the bar or for special occasion the restaurant (candlelit, romantic , expensive lol)
Hope the weathers nice in the UK for you
