Speaking for myself, reasons for not playing RA.
St Andrews/Fife to the south offer a bit better of a destination. Aberdeen seems a bit grim. Not fussed about playing the surrounding courses - Murcar, Newmachar etc. They don't compare to Boat of Garten, Brora, Golspie when building a trip around Dornoch, Nairn & Castle Stuart. Or say Ladybank, Fairmont, around St Andrews.
The highlands to the north offer much better value and much more of a "holiday" off the course. RA seems a relatively expensive greenfee.
I only go for 4-5 days max. Usually to one location. 13 courses in 12 days etc which I read about on here, doesn't really appeal or suit. Lots of other areas/courses to visit before Aberdeen.
