My husband and I have planned our own European trips for years, using Rick's books but also noting where his tour groups are going. (Sometimes I "borrow" from both his suggested itineraries and his actual guided tours.)
I noticed that his tour to Switzerland includes a stay at Engelberg but when I searched his Switzerland guide book I couldn't find even a mention of Engelberg, where I was thinking of going as a day trip from Lucerne.
Does that make sense? Just curious if other readers have noticed. It's disappointing and puzzling.
