Most of the place isn't even open yet - so a school-holiday-full of the general public were there swarming round half a museum.
The gallery for under 7s operates on a timed ticket system, but there were none left for today by 2pm. We did get tickets for some film about the Beatles (what else?!) but they weren't valid for over an hour, by which time we'd had enough and left without seeing it.
The ladies loo appeared not to have been cleaned properly since it was built. The floor was disgusting. One of the taps wasn't working at all, and the coat/bag hook in my cubicle had fallen off. The place hasn't been open a month.
There is a dim possibility that when everything is finally open, in Spring 2012, this will be a decent museum. But I strongly suggest you wait till then.
