Congrats on your trip. I have four kids (all girls) and we have gone in 2014, 2016, 2018. Each of those years – one of them was old 3 or 4 years old. My personal rankings of parks for 4 year olds:
1. Magic Kingdom is number 1 by a mile. So much to do in that age range. Can’t get enough time in that park.
2. Animal Kingdom is fun for a 4 year old. You can’t do Flight of Passage – but NRJ, safari, Kali River Rapids are all winners + two great shows (Lion King and Nemo). And the playground is incredible. Four year olds love that playground. Be careful of Dinosaur, that didn’t seem to spook the kids more than any other ride. Its not that its fast, it’s the show elements that they didn’t like.
BIG GAP
3a. EPCOT – So EPCOT gave my younger kids problems.
- In 2014, I put my then 4 year old on Test Track as the first ride in WDW. She was scared to death and then refused anything but gentle rides the rest of the trip. Lesson learned for me - Don’t start with intense rides if your kids aren’t used to them. Start slow and work your way up on the first day of a trip until you know their limits
- EPCOT also gave us problems in 2016, because my then 3 year old was “just short” of 40. She wanted more rides, but there weren’t that many of them.
- EPCOT winners – Spaceship Earth, Turtle Talk, Nemo, Frozen and surprisingly Living with the Land were all hits. Test Track and Soarin if they are tall enough and are up for the thrills. We tried Agent P, but it was so hot (mid-afternoon September) that they quit. Probably better in October.
3b. Hollywood Studios – Winners – Toy Story Mania, Alien Swirling Saucers, Star Tours. The shows are kinda mediocre. Hollywood and Vine is good – but only if they know and like the characters at that meal. Some fun character meet and greets at the studios too. In 2018 my 3 year old adored BB8, and has continued to talk about him since then.
Obviously, I don’t know what the crowds would be like at Galaxy’s Edge, but is your son a Star Wars fan? In general my kids get a kick out of seeing their favorite characters. Are you going to have park hoppers? Maybe combine EPCOT and Hollywood Studios?
