There are not that many homeschoolers and we have gone for HS days.....it is NOT crowded with hsers, but January does bring in huge Brazilian tour groups! It still isn't bad.
It is typically the 3rd week of September and the 3rd week of January. It is $160 or so for a 5 day hopper and 4 vouchers to the water parks/and/or DisneyQuest.
Even though the actual hs days are the particular week, the passes are good for the week before and the week after just in case you can't make it the actual week of the event. So you have a full 21 days to use them, although they are only good for 14 days after you initially use them, if that makes sense.
These passes have RUINED my kids.....before they had visited Disney Quest or the water parks they were blissfully unaware of them.....now they are a bit upset this year because we told them we are ONLY buying passes for the 4 parks (APs).
I have never been to HS days in September. My husband's work schedule doesn't allow him to go then, so we haven't been. Many like Sept because of the
free dining, but we prefer the weather in January! We are also a family of 5 and like to stay off-site in a condo for less.....
