I am familiar with the Atrium having stayed there for a few years now. I agree with Islandgem's suggestion that the Atrium is child friendly and the Buccaneer Beach Bar great for family nights. The resort is relatively easy to navigate and having the Greenhouse restaurant on property is also a bonus for evenings that you want to dine close to your room. Another thought I had is that the balconies have fairly high, solid walls which might be a plus as a safety feature for your little one. Good luck with your search.
