Hiya Kaitlin,
Welcome to planDisney! Thank you so much for your question about the most out-of-this-world experience in Batuu,
Savi’s Workshop-Handbuilt Lightsabers!
To avoid detection by Kylo Ren and the First Order, Savi keeps her lightsaber operations incredibly small, which is why they only allow one Guest to accompany the builder. I wasn’t sure if this rule extended to younglings, so I reached out to a Cast Member. According to the Cast Member, your little one would count as one of the Guests, so unfortunately, only one of you could accompany your husband to this experience. Sometimes the Gatherers can make an exception if the builder is the only parent/guardian of the child available, but this is done on a case-by-case basis. In this scenario, you would need to speak to the Gatherer at check-in, and they could make the exception if you needed it.
I hope this was helpful, Kaitlin. If you and your son want something to do while your husband is building his lightsaber, I highly recommend taking the journey to
Toy Story Land. Woody, Jessie, and Buzz Lightyear can often be found taking pictures with Guests, and it is sure to put a smile on your little one’s face.
Please come back and see us if you need anything.
Happy Planning,
Ashley F.
