There are TONS of things for toddlers to do. Our son had a blast on his last cruise... he was 18 months at the time. You can always take him into the Oceaneers Club on a visitors pass. You have to stay with him the entire time but there are a LOT of things to do. Best to check the schedules or ask the staff their to see when the best times to go in are.
Our son loved coloring and doing crafts with the bigger kids. Not to mention climbing the little sea-life sculptures. He danced on stage too!
The nice thing about most of the rooms is the pull across curtain. DH would stay in the room and read and whatnot and I would go to shows...then switch off... Our son will try to stay up late with the adults too...so don't worry. Usually I wear out before him!
The splash pool is open late, the movies... We enjoy RUNNING down the halls...every hall...at LEAST 10 times. There are lots of windows to look out too. We were ultra nervous last time about balcony time... but he did well.
I bet your kiddo wears out and will sleep just fine. We requested both a port-a-crib and bedrails. He is in a toddler bed at home but I doubt he will want to sleep in a big bed on the ship...so we got the crib just in case!
Disney with a little tot is actually fun!
Oh yeah, our son REALLY enjoyed the towel animals... he would just giggle and make animal sounds. Ice carving was neat..and of the dances...
It should be an interesting trip....
