Hi Marnie! Thanks for visiting planDisney.
I took a look at the
Refurbishment Schedule, and you are correct that at this time
Space Mountain in Tomorrowland at Disneyland Park doesn't appear on the list. It can temporarily close, however, which sometimes happens, but I expect you should be able to enjoy this iconic Attraction on your visit.
The reason I suspect you don't see times available for your park day is Space Mountain is transforming for
Season of the Force. Space Mountain will have an overlay, becoming Hyperspace Mountain. We enjoyed this overlay as a family last year, and while I always love Space Mountain, I thought the overlay made it an even more epic experience. I hope you get to experience it too!
Even when a beloved Attraction undergoes refurbishment, there is always more to explore than you can hope to squeeze into one magical day. Since your visit coincides with Season of the Force, you'll have several new experiences to try, including themed treats and beverages and a new saga for Star Tours - the Adventure Continues in Tomorrowland. Whether Sith or Jedi, you might want to check out the merchandise too. There's something for everyone! Even the scruffiest looking nerf-herders.
May the Force be with you.
Elizabeth
