Hi Anna
I have had a look through the itinery and it looks like a very good deal
The only things I would like to point out is that weather in Scotland is unpredictable at best, so bring your waterproofs even if its sunny!
Also, the last item 'Golf at St Andrews' you can play on any one of 6 of the courses.....
I expect that as you are travelling so far that you really would like to play on the old course and not one of the others, just make sure its up to you to choose which course you play on and not picked as to which one isnt busy at the time. It would be a shame to lookforward to playing the old course all holiday and be dissappointed.
Other than that, have fun
