Do not do AI but from observations would say Divi for small kids.
1. All of the units are very close to the ocean. At La Cabana will have a long walk and cross a road to reach the beach. La Cabana does have the better Pool if you will do that instead of beach.
2. Have some watersports at Divi you can do.
3. Beach area is good.
4. If teen age than La Cabana is better.
