I have an unused 4 day park hopper ticket that was purchased in 2015ish or so. It was before the date specific tickets came into play. My husband and I are going to disney next October for 8 days. Can I still add days to that older ticket like you used to be able to? And is it still the case that it is better to use one day first and then upgrade the ticket cause then you only pay the difference between a 4 and 8 day ticket at the current pricing? I’m not overly concerned about fast passes cause we will have our 1 year old daughter with us so we aren’t trying to get any of the big headliners cause she obviously won’t be tall enough to ride them.
