Greatly enjoyed this tour of Alcatraz. It was a bucket list item that didn't disappoint. That said.... the tour provider. I am specifically referring to the local company sub-contracted through Viator. The company offered very little communication, no way to contact directly and was nowhere to be found for the relaxed lunch part. We were not confirmed until 1 day before the tour and also came to find out that they were more much expensive than even the JW Marriott could offer the same slot. Viator itself handled our disappointment well and offered a refund for the food vouchers. Refunding $15 per person, brought the price down to $115 per person. This is roughly double what I found for pricing locally and 3X the amount that I would have paid directly to the Alcatraz tour, had I been able to plan.
My personal opinion is that I was willing to pay more due to short notice, Viator handled my issue but needs to re-evaluate using this specific provider.
