In Mexico, Spring is from March to mid-April, depending on the region. Springbreak lasts till the week after Easter. It starts with the university students coming to celebrate the end of exams. Springbreak packages are organized several months in advance, according to their university and holiday dates. Then come families with children in grade school and HS. The wildest parties are at the beginning, and the vibe gets quieter as Easter approaches. The last partiers are mostly 17 and 18-year-old high school students.
