I am looking forward to cruising with my 1.5 year old G'son too! The first thing I double checked was what pool area for non potty trained kids. Not all ships, even in the same cruise line, have dedicated space. I made sure our cabins are close to D/SIL so we could be close to help out. I made sure that we both have balcony cabins so adults could enjoy ocean views or CP balcony when he naps. Hoping we both have a fabulous time & make sweet memories!
