Disney Parks just announced a new annual pass which will be available May 21st, 2019. The new "Flex Pass" will cost $599 which puts it in-between the Southern California Select Pass at $399 and the Delux Pass at $799. The catch is with the Flex Pass you have to reserve some days at the park before you actually go. On days that require reservation the reservations can be made up to 30 in advance.
For those of you who are in logistics, event coordination or strategic planning the Flex Pass may be for you. If used to its full potential you can get approximately the same days at Disneyland as someone who purchased the Signature Pass which costs $1149! It's a gamble but an interesting one!
