Question Is the Mega Mecklenburg Tour from Warnemünde Still Available?

I was planning a cruise that stops in Warnemünde and came across Rick’s guidebook on Scandinavian and Northern European Cruise Ports. It highly recommends the Mega Mecklenburg Tour, but I can't seem to find any recent information or bookings for it. Has anyone taken this tour recently or know if it’s still being offered? I’m really interested in experiencing it and would appreciate any insights or alternatives if it’s no longer available.
