Too many people and the venue can't really handle it. Be prepared for a 2 hour wait to get inside then a different fee to enter the garden. Staff were rude and overworked. Only one bathroom with many toilets out of order. Be careful to not go the wrong way because you can't get back in. The exhibits were OK, but not great. Many areas closed off or under further restoration. Really not worth the trip.
