The park is over on the West side of Scotland (just outside Glasgow). But our little country is so small that its only around 35-40 miles from Edinburgh to Glasgow (East to West)!! In all honesty, its not that well advertised, especially if you are in Edinburgh. In the winter when the park closes, they do take some of the rides on tour. Its quite heavily advertised on TV when that happens, as its around Christmas/New Year time.
Glasgow also had another park, Loudoun Castle. I always preferred this park as they had a pretty decent S&S tower and a Schwarzkopf Looping Star that was relocated from Dreamland in Margate. Unfortunately, Loudoun has now closed
M&D's is OK if you are in the area, but IMO its not the kind of park you would go out of your way to visit.
