It's my second visit and this time with my two children (5 & 8 years old). They thoroughly enjoyed it, from the walk on the easterly and westerly walkways with it's glass section crossing where you can see down below, the audio visual screens with historical and engineering facts (English and foreign languages subtitles) and the engine room. It's a fascinating building and we'll worth a visit. I bought our family ticket online in advance and avoided the ticket office queue, meaning fast entry.
