Given a travel related situation, and given a specific question about the situation, summarize the question into a title

We are going to spend 2 days in London in mid-December and we wonder if we should buy the London Pass which is £46.00 per day per adult. It is not the first time we have used this kind of pass and have always been satisfied with it in the past. However, this one seems pretty expensive to me. Would I save much money by paying the £184.00 for the two days in London?

Is the London Pass worth the price?
