Agreed, of the two, it seems a lesser evil (though I am bored of Buzz now as we have been on it so many times in Paris, WDW and DL, and once a trip is enough for me whereas my son wants to do it again and again - we have only seen Stitch once).
It just seems strange timing to refurb any child friendly attraction during school holidays. There are several weeks where no European country has school hols.
