For those who have taken the Basque tour (or are familiar with the area):
Is it worth the additional cost/heat/crowds to take a July 8 or 10 Basque Country tour, vs. the June 21 departure? I think witnessing the running of the bulls would be an amazing cultural expense, but aside from the much higher tour cost, I also don't want the other stops to be that much more crowded and hot. (Or is there no major difference between mid-late June and mid July?)
