Agree to disagree
I would not base my decision to visit TDR on whether Pirates and Space are open or not
Depending on how many days you go to the park you might miss out even if they were operational ( schedule conflicts, downtime , etc)
Trying to pick a vacation time based on a refurb schedule is tricky and usually a frustrating venture.
I understand that the title of Space Mountain does not mean each ride is the same
I found Paris to be a very uncomfortable ride - WDW is very different ride vehicle than DLR and does not come close on sound - and HKDL had a Star Wars overlay when I rode it which made it different than DLR
And of course SDL does not offer the ride - but Tron was a very acceptable alternative
Surprisingly it is the TDL version that I have not had the opportunity to ride yet - it was available both times I was there but my timing was off and it was skipped.
