The tour was okay, but I had a problem convincing the driver Riga City Tour at a stop not the first stop near the bridge to accept my Voucher. I showed the local phone number Your local contact is Red City Buses AB on 371 6762 7572 given in the voucher, but unfortunately it was different from the one in the pamphlet. So, he rejected my voucher. I had to walk to the first stop starting point near the bridge to see if there are other red buses luckily a person from Riga City Tour accepted my voucher. Bad experience indeed! I wonder why the driver did not recognize the name of the company, 'Red City Buses AB'. May be the name 'Riga City Tour' should be displayed in the voucher instead of 'Riga Red Bus' to avoid confusion.
