Plan nothing other than beach and pool.
Then as the days progress, maybe a trip to the butterfly farm, the donkey sanctuary, the ostrich farm. All of those places are pretty reasonably priced.
A round or 2 of miniature golf over at Adventure Golf is fun for the kids.
There's a bowling alley near the texaco roundabout.

My guess is that the kids will be very happy playig on the beach and participating in lacabana's kid club activities you won't need much other activities.

I 2nd Byran's "must do" Jolly Pirate tour.
There will be coupons in the bag you will receive at the airport.
