I don't care how much you factor in for inflation and the increase in value of the pound v. the dollar, that price is outrageous.
On my trip to Scotland last year, we played 8 more courses, stayed in more luxurious accommodations, stayed longer, still had our own driver and bus for the week, and our trip cost less than that INCLUDING the airfare!
Not to mention, how do you have a GCA trip of Scotland and skip Muirfield, North Berwick, and Gullane?
