Sean -
Visitor green fees at many, if not most, of the courses in the Highlands have tripled over the past 20+ years.
On the other hand, a visiting 4-ball wanting to play Golspie twice could have one player join as a Country Member (310 pounds) and have the other 3 players play at the guest of member rate (20 pounds) twice.
310 + 60 + 60 = 430 pounds, divided 4 ways over 2 rounds equals = 53.75 per player per round.

p.s. It would not surprise me at all if there are wines that have doubled or tripled in price over the past 20-25 years.
p.p.s. Link to good blog on UK green fees. Of the Top 100 UK courses, only 11 of them charge less than 90 pounds for visitors.
