We quite enjoyed our excursion to Neuschwanstein this past March. We did the “hike” because the bus was not operating during our visit due to weather and we did not want to do the carriage, which is not as romantic as it sounds.
There was some snow on the sides of the path, which our 4 kids loved. The “hike” is not too challenging and was a nice contrast to our other tourist activities in Munich proper. We did the tour and, while the tour is rather bland, I thought there were some nice things to see on the inside. That said, it does not compare to some other palaces, churches I’ve been in. There are some nice views from various terraces and some nice views just outside the castle of the surrounding area.
I recommend it, even if you aren’t able to do the tour. Maybe, as others have said, you can see the inside of Hohenschwagau.
