Viator: Worse guided tours you can get.

I recently booked 3 guided tours via Viator. Was so excited to take my sons on an oversees trip. It took some savings to afford the expensive Viator guided tours to give my sons the full benefit of the experience. What a disappointment! The guides see how quickly they can get the trip over-and- done with. "I will release you soon", was a common comment. We paid and are excited to see the Coliseum, Vatican and all they want to do is to let you off on your own to "explore" it all. Don't waste your money by paying 3 x the fees and not getting any value.
