Booking theme park days and tickets

[myaquarium]

Wondering what are the procedures around purchasing tickets and booking theme park days.
Obviously you need a ticket to book days at park.
Do the 14/21 day tickets still expire at the end of each year.
Watched the lodge guys today and they have repurchased annual passes which only become active on their first visit at a park for a full 12 months.
They don’t have an expire date on them so can be activated anytime til 2099.
Is it the same for 14 day tickets.
What other ways can you book your theme park day entrance.

I’m not sure about the annual pass, Mose Tickets purchased here have a shelf life 😀 Once you have tickets it’s my understanding you can book park day 🤔 I’m sure someone more experienced will know 👍
