It will have to be a few as there were so many inspirational moments:
Walking through the rainforest on kilimanjaro was eerily beautiful and the sense of achievement for my son to get to the top of where we walked to was great.
Meeting the Chagga tribe was really nice and visiting the hidden gem of the waterfall, where we walked across to the bottom of the waterfall through the river with our trousers rolled up!
The safaris were incredible I was delighted to see so many different animals including; a herd of over 50 elephants so close they touched the landrover, a cheetah basking in the sun and on a hunt, lions lazying about, a warthog getting chased by and fighting off 5 hyenas - to name but a few we saw so many others.
The Kichanga lodge on Zanziba was gorgeous, the beach was pure white sand, the sea was warm and full of fish (if you want out to the lagoon with a snorkel -definitely recommended) and the pool with hammoks ready for when the kids want to plat and you want to relax.
The history of Stone Town is fascinating and well worth taking a tour if you can and we also took a trio over to Prisoner Island where we saw the giant tortoises, then we went snorkeling in the reef, it was fab!
Make sure you have comfortable footwear for walking. Take warm clothes as well, I only took one warm top thinking I wouldn't need them, the nights and mornings are cool enough on Tanzania to need something. Plenty of insect repellent and suncream.
I was really pleased that I decided to buy and take a really good camera with a good zoom, well worth it.
I regretted not taking a book with me as the nights lent themselves to some reading.
