Wow, we work very hard to provide a good experience and to educate so, when we get a review like this it causes us to scratch our heads in amazement because its not even close to what our clients say about us. I actually take personal offense to our van being so-called filthy - funny nobody else that day lodged the same complaint. Sounds like this person wasn't a history lover - it helps to be one when taking our tour or it could be a long day. We NEVER cut a tour short, if anything its always over the allotted time and as for the cracked windshield it happened that morning but instead of cancelling the tour we went ahead with it not to disappoint our clients as long as it wasn't a safety hazard. I've learned that you can't please everyone but, thanks for taking the time to provide feedback unfortunately, we can't correct this complaint because we see it as internal within this person, however the windshield has since been fixed. Hopefully this person learned a nugget of history.
