Two weeks surrounding Easter are two of the three most crowded weeks of the year (Christmas is the other) and things do get fully booked and you can have parks closing, particularly MK, to new entries part of the day for some of those days. The two Easter weeks and Christmas week, for crowd size, essentially make every other week of the year, even other holiday weeks, look like off-season. Many years ago, they used to publish average daily park entries to MK during the different seasons, the numbers were approximately: most off-season months 25,000 to 35,000; most spring break weeks other than the two Easter weeks 50,000 to 55,000; summer months 60,000 to 65,000, Easter and Christmas weeks 85,000 to 100,000.
