The second thing you'll notice is that you are underdressed.
Unless you are adorned in your full Flamenco ensemble (which you have been planning all year), you will stand out. But that won't stop you from having an amazing time. Take in the beauty and prepare yourself for some serious eating, serious drinking, and serious dancing.
And when those become exhausting, find some shade and do some serious people watching.
