That's a really good point for trip planning,rusty.
I know that here at Carnoustie when booking tee times online there is a question and drop down for "How many caddies do you require?"
There are still an awful lot of Scottish courses that do not do online booking, even for tee times, yet however.
The tourist board has identified this and I hope they take notice of golfers (modern) desire to book online.
If anyone ever wants the Carnoustie links management (3 courses) booking site then it is
