Donna don't worry i went 26th nov in 2000-it was baking!It was between 24-27c every day.We never needed a jumper apart from the evenings-and i'm someone that does not part with a jacket easily I was considering doing nov 06, but for me it has to be school hols, due to the kids.All rides will be a walk on.You'll have a brilliant time
we loved DC too.As an alternative if its just a activity with a dolpin you are after why not try a dolphin experience at epcot.its totally different to DC and a 50% cheaper if you are on a budget.
