This pass is well worth the money if you enjoy historic castles and stately homes. It gives you "free" entry to all National Trust properties, all English Heritage properties, plus a lot of those expensive private large historic homes and family owned castles, etc. We've purchased the 30 day one for several long trips and it quickly paid for itself and then some. It's nice to be able to have a quick tour of some interesting place when time is short (and you wouldn't even stop IF you had to pay!). Look up some of the places you think you'd like to visit on the internet, add up the cost, and see if it's worth it to you. One word of caution... if you're a family with children it MAY be cheaper to skip the GBH Pass and pay the family rate as you go. Have fun!
