Good job, nice photos.
I've been there once (or twice?, can't remember) It surprised me on how they well they run the zoo and the park (yes, including those mechanical rides). I did give it a try. For circus, I remember I sigh after watching coz I was holding my breathe during the show and that was the best circus I've ever watch, though I watched a few only.
Overall I give a thumb (yes a thumb, not other finger) on the Hotel + Park + Zoo.
