I have not been on the Destiny before but do know that it has 3 pools. 2 are on the lido deck and neither is adult only. The main pool area is one of Carnival Destiny's most popular features highlighted by the winding, 214-ft.-long water slide. The deck around the pool is laid out in levels, creating an amphitheater-like effect. There is also open deck space around the aft New World Pool, with a retractable glass ceiling. The 3rd pool is on the spa deck but not sure if it is exclusive to spa users but there are 2 coed whirlpools.
