The castle, the view of it, and the view from it are incredible. While it is not as opulent as Schloss Linderhof, in my opinion it is more beautiful. Photos are not permitted inside the castle. There is a restaurant halfway up the path if you need to stop (walk or a carriage ride for a fee). We walked, I think it took about 20 minutes.
Panorama Tours bus from Munich, 41 euro per adult plus 12.50 admission to Neuschwanstein. Time was limited due to tour schedule.
If you can get there buy other means, I would suggest that. It will allow you time for other things such as a walk to the bridge above the castle, a visit to Hohenschwangau and a leisurely meal.
