The San Patricio - Saint Patricks week long celebration is supposed to start 10 days before Saint Patricks Day ..... and that would mean it starts tomorrow the 7th. Then we have the last day of school on Friday to start the Semana Santa vacation and that is for two weeks.
The carnival rides are set up in their usual place and I assume are open this weekend but I haven't been downtown at night. I'm not sure when is the big final Castillo night .... and there might be one almost every night. In the past, most of the surrounding communities will take their turns building the Castillo structure so there is lots of variety. After the San Patricio party, Melaque will be flooded with Semana Santa vacationers. I suggest getting all your important business taken care of before the craziness.
