We made lots of trips to Disney but never for more than 8 days at a time. We're considering going this spring and would need a 12 day ticket (2 adults and 1 four yr old). The website only offers up to a 10 day for $1109 and the annual pass cost would be $2025. Is there a way to add on days to the 10 day ticket or would I have to purchase an additional 2 day ticket for $586?
