We bought the three-gallery ticket and followed the advice to get there early (about 9.40am) so were #7 and 8 in the pre-bought ticket queue which quickly became very long. Entry is actually very quick and efficient. We spent 6 hours in the gallery and loved the whole thing. Despite it being a Saturday there weren't many rooms where we felt over crowded. The cafe is a bit painful with a slow and complicated approach and not enough seating. The shop is excellent. A not to be missed experience for any art lover.
