There is plenty of choice here, if you would like to send me your telephone number (or if you prefer, an e-mail address and I'll send you my number) we could talk it through if it helps.
As an indicator, I'd probably go Hunstanton, Wells Next The Sea and then cut inland to Fakenham, Swaffham and Snetterton on the way to Silvers (avoiding the VERY slow and busy coast road from Wells to Great Yarmouth) and then visit Krazy Horse and home via the A14/A1 afterward. There are good eateries at Hunstanton and Wells, Snetterton has its own cafeteria that is usually open on Trackdays (and free to access unless racing is on) whilst the café at Krazy Horse attracts visitors from as far as the midlands for its food!
I don't often work now, so if you want I could meet you for some of the route? (I live between Watton and Swaffham).
