Rosevelt's Special tour or Greg's Safaris plus beach?

My family of 5 (3 kids ages almost 5, 7 and 9) will be on St. Kitts for a stop on the Disney Wonder in January. I'm looking at both of these tours and trying to decide. I know we want to see the rain forest (unless we're better off seeing it on Antigua). Both of these tours drive into the rain forest, but Greg's adds on a beach stop while Rosevelt's adds on Romney Manor and Brimstone Fortress. Which do you think would be best with the kids? Or would we be better off doing a boat tour instead? I'm struggling with the choices here! Thanks for any info you can give!
