Enough activities for boys on HAL?

[gopackgo]

We are planning a family Christmas cruise. We are considering RCCL, Princess and HAL. I am one of the aunts. There will be 6 kids from age 4 up to 15. 3 boys, ages 10, 11, and 12, who like a lot of action and sports activities. (What boy doesn't, right?)

 

I am sure they would love RCCL. But I am also looking at Princess or HAL. Are there enough activities on Princess and HAL to keep these kids (boys especially) busy and occupied so they don't get bored?

 

I am thinking perhaps the parents and the aunts and uncles might like the food and service on the Princess and HAL a little more plus on HAL, there are less passengers. (1800 vs. 3000).

 

Thanks for any help!
