Where to start? If, like me, you are a fan of Brunel and his work, then SS Great Britain is something you simply MUST go visit! You literally get to go over this iconic ship from bottom to top, inside and out! One thing I will say is don't wear anything too warm for your visit. To conserve the ship, inside and out warm, dehumidified air is circulated constantly throughout the ship and under the glass "sea" covering the dry dock. The atmosphere under and inside the ship is, of necessity, literally as dry as a desert! It is not unbearable by any means, but you truly won't need a coat!
