We were there on a cold December day in 2019. Previously I had been here in April 1988. I couldn't believe how Neuschwanstein had changed, and in my opinion, not for the better. The tour is now is rushed, You wait for your appointed time, and they pack you in and rush you through. The tour guide we had was not inspired, these guides must do this same thing 8x times a day and repeat the same spiel over and over and over again. When I was there in 1988, our tour consisted of a knowledgeable guide and a group of no more than 10 people. We saw things in 1988 that are no longer part of the tour now. Much of the grounds in December was off limits-- I don't know if this was due to snow or the construction that was going on-- so picture angles were just from the lower observation level. If possible, you can climb up to an upper view and get a nice pic of the castle looking down on it.
In 1988 the view of the lake was amazing, today it is filled with high rise hotels or something. The view of the lake is obstructed. The shops around here are TT's. I saw something in Munich that was 7 euro at the market, at the Castle it was 14 euro! Same exact thing.
The Castle in my opinion, has become a casualty of its own beauty and uniqueness, and relegated to a an assembly line experience and no longer is given the time or credence to its history.
Hopefully if you get tickets it can be early in the day and then you have the rest of the day to tack on another stop somewhere in the region that would be less touristy.
