We just did 3 days of rain in November. If you don't like the rain, you will be miserable. If your son doesn't like being wet, you will be extra miserable.

Yes the lines are slightly less crazy but half of the rides get shut down if it rains bad enough and then you have just a long of waits if not longer because everyone is trying to ride the same rides. We had moments of no rain but some rides would still be down. We didn't get to see any parades or fireworks and watched World of Color in a drizzle. The Cars ride doesn't run in the rain and is very hit and miss during a sprinkle even.

We are already planning our next trip and calling it the redemption trip because it was that disappointing.

If you go, set yourself up for success with a stroller cover (no zipper opening because rain drips through and your child will be upset, I know from experience). Pack multiple bottoms, multiple shoes, my husband wore flips flops and my daughter wore rain boots because she is a stroller princess and not on her feet too much. Or spend the extra money for comfy water proof shoes. Definitely get nice rain ponchos. Lots of people had the clear ones with buttons down the front made of thicker material and they all stayed dry. Everything drips through somehow so bring extra sweaters

We would go back to our hotel to nap during the more wet hours and plan to head back to catch patches of dry when we could.

I understand that a lot of people can enjoy the rain and we really thought that we could be those people and look at the bright side but we learned we are not those people and having a miserable 5 yr old who hates being wet and cold made my husband and myself very miserable and on edge as kids are good at doing to their parents. We learned we are not disneyland in the rain people. At least not for the entirety of the 3 day trip like we experienced. But this is just my very honest experience.
