We just stayed at Beach Club for my nieces first trip in September, and she was 18 months old. I must say, we do Hoop Dee Doo every trip, so we didn't want to skip it and she actually LOVED IT, even at just 18 months old! She had a ball! I wish I could upload the videos to show you how much fun she had. The CM's there had so much with her, she was clapping the whole time, they put the strawberry shortcake on the table and she immediately grabbed a spoon and helped herself LOL! It was one of the most memorable times of the trip and we are excited to bring her back there this September. It definitely isn't a waste, especially since they are free until 3.
We spent each afternoon at the pool at BC.. that pool is great for little ones. We found BC to be perfect for us. We went to Epcot multiple times, so having that short 5 minute walk there was very convenient. We also went to DHS more than once and we took the boat each time, and that was great.
At the parks, we took her on everything that did not have a height requirement. She loved every ride! We made sure to do the Disney Junior stuff at DHS, met the characters there and did the Frozen show as well. We also did some character meals. We got her first haircut at the barbershop on Main Street on our first full day, right when the park opened and that was the cutest experience.
