Many European tourists travel to Spain for their vacations because they think it offers guaranteed sunshine. In reality, the country also suffers from rain. Yes, the summers are usually hot but rain may set in at inconvenient times. This is out of the control of any tourist company.
Typically, one reviewer didn’t accept this and criticized the weather. “It rained,” they wrote. “We didn’t know that it rained in Spain.” We don’t know if they wanted the tour operator to wave their magic wand and make it go away. Or perhaps they thought they had a time machine (via Reddit). Maybe if you don’t know that it rains nearly everywhere around the world, you shouldn’t be traveling to another country.
