can only give you my experience,as we found it.the 1st time,we went on the 31st,was in 2006.we were attending
MNSSHP,but it was also,the only day,we could book breakfast,at the castle,so it was going to be,a long day.however,it was great,because all of the rides,were walk ons.the crowds,were really low.my niece & grandaughter,went on space mountain,about 5 times,on the trot.we all rode splash mountain,4 times.just got off & walked straight back on.we loved the low crowds!
next time,was 2008,although we didn't go,until 4p.m this year,due to the grandsons,being little,but at that time,we walked on splash mountain,haunted house & big thunder.
i would say go & hopefully enjoy,the low crowds.will it make a difference,it being a saturday,this year,i really don't know!
