Open air but has cameras dotted around the place.
20 mins walk into the centre of Leeds but well placed for ITV studios.
Remember - you only have to pay up to 5:30pm. So, if you arrive at, say, 4.30pm you only have to pay for an hour even if you're staying much later. Some folk don't realise this, as can be spotted by the high amount of rejected coins normally left by folk who don't check their tickets! :D
