We took our daughter at 10ish months. Great trip! We did 5 days which for us worked. Took it slower but still got almost everything in. We got often enough that if we miss or skip something it’s not a huge deal. She liked the characters, clapped and loved rides like small world, and shows with music and signing.
With baby two we are actually thinking of going closer to the 6/7 month mark. My reasoning being at 10 months she wanted to crawl and stand a lot, at 6/7 months she was less mobile so hoping the wanting to get down phase won’t have started yet.
If you end up driving it won’t be an issue but I would plan on using
amazon prime now for most items you need so you don’t need to bring everything and can order as stuff is needed.
Have an amazing trip!
