Enjoyed it, very informative for first time DC visitors. The only problem was that it wasn't very well explained where the stops were to get on at first. Would definitely recommend it, and Ellie was a pro driver/guide!
We had a very hard time getting back onto the Trolley once we got off because we had my husband's scooter. Every time we got off it would take us more than an hour of standing before we got a trolley that would take us.
We really enjoyed the Old Town Trolley tours and wish we would have used the service earlier. The only problem we had was the processing of the electronic voucher. We had to go to the welcome center to have the voucher processed and get our day ticket. Wasn't a big problem since the tour drivers let us ride to the welcome center.
