Last year was our first time going during the week of Columbus Day. I should preface by saying that we normally go in September - the week after Labor Day - which has been described as the least crowded week of the entire year!!!! With that said, we were quite surprised at the crowds. The waits for the more popular rides were easily an hour and MK seemed very crowded. Again, we are use to no crowds so I guess anything more then that will seem crowded. I'll be glad when we get back to our September rountine!!!
