We booked this service for my husband's birthday. The tour was fantastic. It was extensive, stopping at all the monuments we wanted to see. We were able to customize the tour as well, spending more time at some monuments and skipping or shortening visits to those we were less interested in. The limo is able to park very close to each monument, much closer than we could have if we had driven ourselves. The driver was polite and helpful. Wear comfortable shoes because, despite the proximity to the monuments, there is still a lot of walking involved in exploring the monuments themselves. We did our tour at night and the monuments are gorgeous when lit for evening. The driver can tell you a few facts about each monument, but he was not a "certified tour guide" so if you want that much detail, this is not the tour to take. But if you want to see DC in absolute comfort, this is the way to do it. The limo will pick you up at your specified address in DC, drive you for four hours to the monuments on their list which is customizable, and then drop you back off at your specific DC address. If you want something to drink or eat, bring it yourself as only waters are provided in the limo. Definitely worth the money. Best way ever to see DC!!!
