We went last Monday - it wasn't too busy at all and there were quite a few Scottish families then but they've now gone back to school!
We didn't do the dinosaur thing as we only had DS2 with us and he wouldn't have been too bothered. From what we could see though it just looked like massive plastic dinosaurs - cost £3 to do that bit - Let me know if it's any good!
It's a lovely day out though and all of the animals & enclosures looked clean and healthy - The Elephants stink though!! Don't miss them Feeding the seals or the Lions/Tigers!!
We went in the afternoon and it was empty down in the children's zoo which meant DS2 could toddle about quite happily!
Me & Dh have been going there every year for 6 years that includes the 4 yers since ds was born. i think its great. not took big, so the kids dont get sore feet, just the right amount of animals and there arent loads of expensive gift shops- ds is content with a mask and a plastic animal- bless
