Dear William,
We are grateful for your feedback. I am sorry to inform that indeed the tour option offered for Mondays for "Bilbao, Guggenheim Museum & Gaztelugatxe from San Sebastian" specifies very clearly that the Monday tour option, "Minibus bilingual tour option", excludes lunch and the visit to Guggenheim museum. Also the price differs accordingly (you paid one third of the tour option that has these two inclusions among many others). It would be quite inefficient from our end to offer a tour that has no way of being completed as it is offered.
However we already contacted with the Viator supplier support system to request a change in the information provided to our guests to prevent this from happening again in future bookings. We are far from aiming to have misleading information that would make it difficult for us to exceed our customers' expectations in our tours, which is the main goal we have in our company.
We have been told that the info will be detailed more accurately from now on.
We remain at your disposal and definitely look forward to hosting you again in the future. Many thanks!
