I have made over a dozen trips to GB&I. One trip worth considering is to fly into Bristol and play courses in Somerset (Burnham and Berrow), Devon (Westward Ho!, Saunton), Cornwall (St Enodoc, Trevose), and if you have time, wander into Wales (Porthcawl, Southerndown, Pennard). The golf is wonderful, and the driving is relatively benign if you don't mind driving on the left. It can be crowded in the summer, but September is a great time to go, and the green fees at most of these courses are reasonable. there are other courses you could add.
Tommy, Those are two good trips.
I have the following two on the drawing board:
Camberley Heath £98.00 Harry Colt
Minchinhampton (Cherington) £30.00 Martin Hawtree
Minchinhampton (Old) £30.00 Robert Buff Wilson
Painswick £22.00
Kington £31.00 CK Hutchison
Church Stretton £30.00 James Braid
Cleeve Hill £40.00 (30 PM) Old Tom Morris
Tadmarton Heath £60.00 Harry Vardon
Frilford Heath Red £115.00 (or 150 for both) JH Taylor
Frilford Heath Green £115.00 (150 for both) Frank Pennik
Huntercombe £120.00 Willie Park Jr
Swinley Forest £250.00 Harry Colt
Ganton £250.00 Harry Colt
Alwoodley £225.00 Alister MacKenzie
Moortown £140.00 Alister MacKenzie
Lindrick £125.00 Old Tom Morris
Fulford £125.00 Charles MacKenzie
Sand Moor £90.00 Alister MacKenzie
Reddish Vale £45.00 Alister MacKenzie
Cavendish £55.00 Alister MacKenzie
I always hire a car and drive. IMO, the cost of hiring a driver for four or fewer players is cost prohibitive and it's really not too difficult to get used to driving in GB &I.
