long lines to Sisi Museum in mid September?

I'm trying to plan my day at the Hofburg in Vienna and am somewhat reluctant to buy all my tickets ahead of time. I do have a Spanish Riding School ticket for a performance which is at a specific time. We want to see the Sisi museum and the National Library. Are the lines to buy tickets and get in likely to be long around mid-Sept, such that we can just buy tickets when we get there rather than before we leave home?
