Five Hours at The Hermitage with Gold Room

I changed my shore excursion. I will be overnighting in St. Petersburg the end of September. I am sailing Norwegian Cruise Line and go through NCL for shore excursions.

The Hermitage is at the top of my must sees. I had signed up for Three Hours at the Hermitage in the evening with a Panoramic look at St Petersburg in the morning of the same day.

I cancelled The Panoramic Look as well as the Three Hours in the Evening but added Five Hours at The Hermitage with The Gold Room for the first day.

Has anyone taken this shore excursion or a similar one? Has anyone taken this one through NCL.
