I have used the London Pass and gotten the value from it. The website lists what attractions it gets you into, and the savings can be significant. IIRC there is also an option to add public transportation to it which depending on your case is potentially valuable as well. You also get to jump the queue in several places.
Of note, we picked our passes up at Waterloo at the tourist desk upon presentation of the voucher obtained online. No problems whatsoever.
