Hi Deb, glad you thought the tour was informative! I apologize for the sound issues in Grand Central. Since the Terminal has increased the volume of their announcements and with masks our guides have faced challenges. We have ordered a whole new listening system to outfit every tour with the ability to hear the guide through a discreet earpiece and those are arriving within the week. Since you did not benefit we would be happy to reschedule on a tour that is outfitted with these devices whenever you are able to join us. Please contact us at
[email protected] and reference this review. All my best!
