Please note this Hop On Hop off tour is only for 1 day only not 2 days as advertised on Viator. Very disappointing in the Viator customer service from my query as they replied saying it was still valid for 2 days and did not follow up further with the agent and listened to my updated information. The 2 day offer is no longer offered by the bus company however the offer is still saying 2 days. Buy directly the 1 day pass from the bus at any stop on the route. No need to buy from the agent or on Viator.
The tour is great, I enjoyed the sights and please note their is also a north Goa day tour to buy from the bus.
