I am a Spanish teacher from Michigan and I will be taking my first group of HS students to Spain in less than 2 weeks. We will arrive in Madrid on Good Friday at 2:30pm. I would like my students to see the parade, but I don't know where to go or when it begins. I'm very clueless on the whole Semana Santa thing as I have never been in Spain in the spring.

Can anyone tell me what time the parade is and where we should go to see it. Also, is there anything else on Good Friday that would interest a group of 15/16 year old americans? Age-appropriate clubs and other nightlife?
