Well, for Europe my experience is limited to one trip on Diamond, the rest of my experience is on the PG. In that case, I do not believe the excursions are over-priced, I think they are very fair. I read Tahitian Princess folks doing private excursions all the time in FP, and I don't think it's necessary at all to go private on the PG. On our Diamond trip was hard to tell, since it was the first trip in the Black Sea, and I was unfamiliar with the norm for these things. But I didn't think they were overpriced either. Guess I'll have to see next summer when I'm on Voyager.
