I grew in Jersey and that was the week we had our Spring Break every year! So its definitely gets hectic... but also note that schools have very different holiday schedules, some having Spring Break as early as March, some as late as the week after you! I think when you are going is on the slower end of the Spring Break rush but its still a peak period. I'm going in early April (8th-13th), which I did last year and it was crowded but doable. But I don't worry about the crowds- I usually go during Christmas and sure its crazy but every year we still manage to get everything done and have an amazing time to do it. Have fun!!
