My son, 24, just moved home from Panama City Beach, Florida, Spring Break Capital of the USA, Spring Break for all schools, nationwide, is a 5 to 6 week period mid March to Mid April, the heaviest is reflected by the price spikes. We have gone 3 times during spring break, around mid to late march, and as a couple with no children in tow, we did notice a lot of kids, and a lot of college partiers, as well as old people like us. The ship is big, room for all to do just what they want. That is why cruising is so great, and Carnival does the best job. Relax and enjoy.
