I agree with you @Theme Park Girl. And you've got to remember @Theme Park Ninja it does take time. I've been running my page for almost six years now, and its only in the past couple of years I've seen a real increase, especially this year. I'm just passing 4,500 likes, and that may not be overly many when compared to TPSN who are about to hit 9,000 likes and has been doing it a couple years less than me. But I've found my own style for the page, know what people do and don't want to see, and I've learnt how to present my posts. I don't post things that are unnecessary that don't directly link to our parks. I know the focus of the page, who I'm targeting and I stick with it. And I think that's why I'm still going and my page is starting to get more popular. It's fine if people don't agree with what I've just said, but that's my opinion and what I've learnt in the past six years.
And it's a shame that some of the smaller pages out there, who do brilliant coverage and have taken some great photos, aren't getting as many likes, but if they keep at it, they will eventually get there.
If you want to keep a page going, why don't you rebrand your current page to Theme Parks Australia, delete all unwanted posts or references to Theme Parks World, or The Ninja. Then you've still got those likes, and find a style for your page, what do you want to show, and stick with it.
Hope this helps you.
