This place was great for us and our 4 and 1 year olds. 1 yo used the portacot.
The Waikiki Banyan had a great pool, playground, BBQ area that our kids loved.
The view is awesome! You can see the pool, BBQ area and tennis court which aren't in the pictures.
The room had everything we needed to self cater. One thing that was great for us was the carpet so our kids could play on the floor.
We'd very happily stay here again. However if you're looking to be closer to the main beach, shops and restaurants and mobility is an issue, I'd suggest staying elsewhere. We were able to pram or carry our kids ok - easier when not in the heat of the day. But walking to and from these places a few times a day did take some time.
Lastly, the free car park was great although best to check the height of your car as it is a low roof - we had a 7 seater minivan (Nissan Quest) which fitted but not by much.
All four of us had a great time at this place and I'd recommend it to another family like ours.
