Conwy is only 1:15 from Manchester airport. As a base, the town has 15k people so no shortage of places to eat and stay, and the club could support group meals. The course is of sufficient quality to have had Mark Rowlinson as a member, which is a great endorsement. North Wales seems to make a great second course and requires almost no travel. For those looking to add on to the trip, Fowler's Bull Bay (highly recommended) is 45 minutes away. Harlech & Aberdovey are under two hours, and Hoylake and the Southport Open courses are a small detour from Manchester.
This one ticks all the boxes for me.
