Would it be boring without a tour?
We’ve been to art museums and it’s been great- but there you have plenty of colour and visual stimulation. I wasn’t sure if my daughter would enjoy it, but she did- a lot. When the tour finished and the kids had had some food and a play, we carried on looking round the museum and it was interesting- so if you are quick to read the signs and explain, why not go without a tour? I must say, Lingotots enhanced the experience though.
If going with kids, you can use the ‘Family Centre’ to store your bags for free as well as sit down to eat. It is down a level, in the corner near an information post.
The shop is well worth a looking at at the end of your visit, too. We bought a couple of great books and bits.
