I am a teacher in the Tampa area and my daughter attends a Florida University and our Spring Break is the week before your cruise. You should be fine. The week before your cruise tends to be the peak Spring Break week.
Personally, my husband and I have always enjoyed cruising Spring Break. Better chance of the Lido deck and pools being quiet in the mornings because the college kids are sleeping and we have early dining (when college kids are napping)🤣
