We did not book tickets ahead of time, but were able to walk in and get same-day tickets for entry about an hour after we arrived. So we had a nice cup of tea and some scones, browsed the shop, and it was time to go into the exhibit.
Laid out like a house in Pompeii, the exhibit was fascinating. We had just been to Pompeii, so to see the artifacts here was a special treat. We could so easily imagine them in place, and the museum did a great job of recreating the layout of the house. If you are in London while this is still going on, we highly recommend it.More
