Easter's a big thing down here. Probably bigger the Christmas. Here it's called "Semana Santa" or Holy Week. Most people celebrate for two weeks and many take their vacation during these two weeks.

There's a lot of partying and a lot of church services. Most houses around me rent for the two weeks and the beach is full of people. Many places on the beach have stages set up for live bands and the music goes until dawn. The house next to me had a live band last night. This morning my coffee cup was bouncing across the end table to the beat of the bass.
For me personally it's a time to make sure my house is well stocked and I don't need to go anywhere. I stay in, driving is really an option. My sleepy little town goes from about 25k to nearly 200K for the whole two weeks.
Easter's never been anything to me, now I'm just happy when it's over.
