The Warner Bros. Harry Potter Tour is EXCELLENT! Unfortunately, we didn't have the full amount of time to enjoy it as the Golden Tour Bus ride took over 2 hours. Apparently our driver was given the task of delivering tickets/envelope to another bus driver enroute. We were told the trip would be about 1 - 1 1/2 hours, but ours was just over 2 hours. Additionally, we were given a specific time to depart the studio, but the bus wasn't at the specified location until 20 minutes later (time we could have spent inside the venue). Loved Harry Potter and will return, but will take the Tube and then the overground rail to Watford station rather than depend on Golden Tours.
