Hi Felix,
We are really sorry that the content of the explanations were not of your liking and that the historical part was boring for you. The tour explains the history of the region, we visit Vitoria which is the capital city of Euskadi, Laguardia, etc so it is a combination of several different cultural and historical locations.
Related to the specific wine explanations, they were provided during the guided visit and tasting to the winery that you visited including the traditional process of elaboration. Moreover, the guide is always eager to explain more details in case you want to ask specific questions. Maybe this was not the right tour for your family since there are other options in private more specialized just into wine and wineries for wine lovers or specialists.
Regarding the price of 70€ per person and 35€ for both of your children, it is quite an economic price if you compare it with all the other possible regular tours that you have from Bilbao to Rioja. And our tour includes as well a tasting of gourmet chocolates, wine tastings into traditional winery caves etc apart from the expert guide & quality bus transport.
We hope at least that you enjoyed the locations, the charming streets of Laguardia, the traditional fine Rioja cuisine etc Our goal is that our clients have a nice time, learn and discover some charming corners of your land and we really get sorry when this does not happen. Thanks a lot for your comments.
