We were there last August, it was extremely hot!!

Yes we got to the zoo as it was opening did that first and then hit the park - if you think how big you may think CP is then multiply it by 1000 you may just have some idea of the scale of the place. We did most of the sites in the park - Bethesda terrace (in the film Enchanted), Strawberry Fields, the boating Lake, Alice in Wonderland statue, the baseball/softball fields, and Belvedere Castle which is a bit further north in the park but definitely work a visit as its very pretty with some fantastic views.

Crown access allows you to go up into Liberty's crown, they only allow so many a day to go up and they were sold out before the day when we were there so if you want to do that you need to book in advance. Our tickets were monument tickets which allowed access to the top of the plinth on which she stands - you can look up inside the statue from the top of there and there again are great views from outside.

Not sure if I can put a link to the place I got my pass from so I'll PM you
