I sent an email to see if an end date was anticipated for the space mountain refurb. I told them we planned to be in the parks March 12-15 and just wanted to see if the refurb would be lengthy or possibly a short one. I received an email back today. Here is the info I received. Just wanted to share.

Thank you for contacting the
Disneyland® Resort in Southern California!
I am sorry to hear that Space Mountain will be under refurbishment during your visit. While no public date has been released yet for when it will be back open, I can tell you that we anticipate it to be back in the middle of March. While I don't want to discourage you from visiting on the dates you are planning to come, I can say that most likely you would not be able to go on Space Mountain for those dates.
We encourage you to come in late March or even April to play it safe if this attraction is paramount to your visit as refurbishments are sometimes unpredictable in terms of when they will come back online for an exact date.... allow me to explain a little more. Safety is our number one concern and we are very big on preventative maintenance. During this refurbishment our Walt Disney Imagineering along with our Leaders in Maintenance and Safety will do a full inspection of the attraction, while we have planned for specific things to be done to it, it is possible that other things may arise during the refurbishment, things that are still in passing condition but would need to get replaced 6 months down the line, for example, would be replaced while it was already offline for the existing refurbishment to prevent another time of it coming offline and to ensure the utmost safety for our Guests.
I know that was a very long explanation, but hopefully, it gives you a little insight into why we do not have an exact date yet. We look forward to seeing you soon!
Have a Magical day!
