I have recently returned from my first UK golf trip.
I can't highly recommend enough the golf, and importantly, the "experience" of Swinley Forest and Sunningdale.
Sunningdale Old is one of my favourite courses, anywhere, while Swinley Forest is one of the greatest days I've ever had. Combine an old world atmosphere, unique club environment, wonderful golf course, great company, and an amazing lunch with a bottle of red, a very special day is guaranteed.
No matter what you choose, you are going to miss out on something special. A return trip is on the cards!
