Hi, Stacy! What is scary to one child might be fine for another, but I can share my experience with you! My daughter is now 10, but when she was around 4 or 5, we took her to
Voyage of the Little Mermaid. I thought it was awesome! But, to my little princess, it was terrifying! It is very dark, and they use puppet-type characters with black lights. My daughter really was scared and we had to leave.
I really don't remember the noise as much as the darkness. To be safe, I would wait on this one, but you know your child best and what will be enjoyable! I am always one to play it safe. With so many other fun attractions, why risk them being frightened. Start with
Playhouse Disney Live on Stage, Beauty and the Beast Live on Stage, MuppetVision 3-D and see how those go. If your 4 year old seems OK, give it a try!
Your WDW vacation will be here before you know it! Wishing your family a very magical vacation!
