Where I am in Alabama, a couple of counties have spring break mid-March and one in mid April. My sister-in-law, who teaches in one of them will be going March 17th-March 22nd. My mother-in-law teaches in another county and has spring break at the same time as my son, which is April16-April 20th. We are going 4/15-4/21. We are hoping for the best and preparing for the worst with crowds. We were not able to get our first choice in hotel, but were able to get the dining reservations we wanted at the times we wanted (actually good dining times). We were surprised! We have been enough times that we know what we want to do and what we can skip if crowds are as bad as we think.
