We cruised with my 2 yr old and 4 yr old in October. We did a 5 night cruise on the Wonder.
We payed for my 2 yr olf to go to the nursery one afternoon so we can do a brunch at Palo's. Since he is not potty trained, he could not go to the big club. They do have open house times, and we were able to take Bayne to the club. He LOVED the slide. Also, we did second dining. This worked for our family, because we would take him back to the cabin for a nap. We only did one show and surprisingly he sat through it. We planned out which characters and he did great waiting. At Castaway Cay, we did ocean , characters, lunch, played games, more swimming, and then headed back to the ship for nap. He did not want to do the sail away party, and we didnt get to see fireworks either.
