St. Andrews Golf and Outlander Tour of Scotland (1 Viewer)

So the wife wants to plan a trip to Scotland in 2020 to see the country including sights from the Outlander books and shows. I think it would be fun if I could include a round at the Old Course in St. Andrews but I would need a guaranteed tee time. I've heard horror stories about the ballot method and I don't want to end up SOL. I know that the St. Andrews links provides blocks of tee times to certain tour vendors. Anyone here have a reliable resource for such a trip? Any advice is welcome.

dont drink the water.

Our 4 some got the ballot 2X in a week. Short straw went straight from the pub in the www hours to the course
