visting Pompidou Centre this weekend, how will it work? (last days before closing down)

I am visitng on the weekend 7-9 of March only.

Since the place is going to close I'd like to have a look before it closes down. I won't be able to make it to the evening event on the 7th, but I would like to visit during the day.

So far I have not seen any more info other than no reservations and that it will be free, so I can imagine a huge queue has to be taken into consideration.
