They are fraudulent and scam artists. Purchased tickets for Kennedy Space Center with your and lunch for a specific day.
Got confirmation. Told to call at least 24 hours in advance. That's the scam. I called a month in advance and there were no places left on the tour or lunch for that day.
I paid and didn't reserve anything. Never told that. Difficult to talk with Viator. Only through very slow emails.
Resolved issue but for a different day and no lunch with an astronaut.
I used Viator due to connection with Trip Advisor but will never use again. They used my money for a month and I hadn't reserved anything.
Product or Service Mentioned: Viator Tour Booking.
Reason of review: Poor customer service.
