We did it in June and absolutely loved it! We all agreed how it good it was and thought it was great value for money in our opinion.
Both our guides (Dan & Millie) were very knowledgeable about the Elephants and various conservation projects for Elephants and they made sure everyone had plenty of time looking at the Elephants and we never felt rushed to move on. It was amazing seeing Baby Stella up close. She's so cute!
We did the 10:30am tour so it wouldn't be as hot and so there was less chance of it being rained off. I think there was about 15 of us on the tour in total. Mostly adults with one family that had a girl around 9/10, I'd say, and everyone was very considerate to make sure she was able to see so I think your kids would love it too. Definitely recommend it.
