Never has Rick had such a diametrically opposite experience than myself when visiting a destination he recommends. We were using Rick's 2013 Germany book so maybe something was mentioned in the 2014 edition referencing a change? I don't think so though because when I left review at TripAdvisor there were other people who did get English tours this year.
My wife and I had a horrible time at Burg Eltz. We were not given an option for an English tour but were instructed to pick up an English pamphlet for the tour. The "queue" to get into the is more akin to a mob of angry villagers but without torches or pitchforks. Nothing about this place is organized. You have to be aggressive and elbow your way to the door if you ever want to get inside the castle for a tour. The walk there from Moselkern was great. It reminded us of being back home in the Pacific NW. The castle from outside was pretty, but the whole experience of being in the castle was dreadful. The walk back was pretty bad too. There were times we had to stop walking because of how congested the trail had become.
I guess I just wanted to post a warning to anyone thinking about seeing it. You might want to expect to not get an English tour at Burg Eltz, and if that matters to you to skip it. There isn't any indication that English tours are available or who to ask to be in an English group. Zero organization and crazy crowds.
We had a much better time at the castle in Beilstein and has no tour at all, but was a much more pleasant experience. Also, Reichsburg Castle in Cochem was also a very enjoyable experience.
