Yes. Its to the point that they even offer a Thanksgiving Feast in a hotel it's so packed. Lighter crowds (though with some rides down) are in late Jan-March.
I went on a Monday, Veterans Day and it was not crowded. Longest wait time was 60 minutes for Space Mountain
It will get busy usually on most holidays. Best days to go are 1st-3rd week, Monday to Wednesday. Thursday-Sunday it gets busy like you expect
I went on a Thursday and it was full
I doubt it but u never know. Call disney they have fantastic customer service and are so helpful and will answer all your questions!
