Not played Saunton East but Westward Ho / Royal North Devon is a must play imo when in the area. The most rugged, natural and made from nature links I have played on. It's maybe somewhat of an aquired taste but if you like links golf in it's purest form you'll love it. I can guarentee you'll not forget 'The Cape Bunker' on the 4th, and the small yet fascinating golfing museum in the club house is worth the entry fee alone!!
I've a vested interest in the place and as a result maybe a slightly biased opinion, as we are working with the course on a bunker project, but for me you've made absolutely the right decision to work it into your trip. This is golf in the raw!!
