The trolley tour was good. It depends on the driver on how good it could be. One driver we were lucky to have twice was a very funny guy (Louis) and made the trip enjoyable. The only problem I had is I printed out the voucher from Viator and the driver didn't know anything about it. I went to 3 trolley booths to get a ticket with the voucher and was told it was all I needed. I got on at every stop it went to and the drivers always said get on but you should turn the voucher in for a ticket. So that part was an inconvenience but the trolley and tour is well worth taking.
