I wouldn't say I regret playing there but my biggest disappointment was at the Belfry Brabazon course.
Still perplexed as to why it was ever chosen as a Ryder Cup venue. Surely GB and I has much better to offer? I hope it will never return there. And it's a golf tourist trap: expensive with a very average hotel. The food is to forget too.
Now for the course, for all it's reputation, it's a cramped and claustrophobic affair. The design is boring, some holes are worth noting and at least look visually good (4th, 8th, 9th), but some are just plain silly (6th) or just bad (11th). The famous pair of 10th and 18th are not especially good, the fun is merely found in reading the plaques that mark famous shots. They do not compete one second with dozens of better holes you find at so many classic gems all around the Isles. A total over-hyped miss. Avoid.
We were a society. They threw us first on their Derby course which is dull, short and lacks character. Thanks. We then took 5.5 hours to go round the Brabazon...
Thankfully we got to play the PGA National course which is fun, visually beautiful, tough, varied and makes you travel in wide open spaces. Inland links style, with lots of options everywhere. (but do not try to catch the 2nd green in two! It's tempting, but the right contour of the green pulls balls in the water, including mine obviously...) Only downside is the 18th which is a bit disappointing. Narrow, over bunkered, watered, but hey, you are then back to the clubhouse and next to the Brabazon...it must be contagious.
This one is a hit and should you travel to the Belfry save yourself time and money and play the PGA course.
