Hi James, please don't apologize for being honest. We always value feedback as it helps to make our tours and our guides better. I am very sorry you didn't enjoy your Underground Subway tour experience with us. The summer time is definitely a challenging time for this tour especially when it is hot both outside and in the subway system. I will be sure to speak to our guide about his presentation and please email us
[email protected] so we can take additional steps to rectify the situation. I am lastly glad to hear you enjoyed your Grand Central tour with John. Take good care!
