Dear Joel,
Best wishes with your West Village tours. I don't have an outside suggestion, but you could see this link (you will be prompted to log in to your GANYC membership account on the Wild Apricot system), and keep your eye out for the announcements for GANYC'S personal liability insurance.
www.ganyc.org/ganyc-liability-insurance-1
It reads, "Enrollment for the 2027 policy year will begin in November. Please email finance@ganyc.org with any questions you may have about enrollment."
The cost will be $85-$89/yr for GANYC's/the NFTGA's personal liability insurance policy.
Sending good luck to you!
