When we visited, there was a lengthy queue, but it was worth waiting. It is a magnificent attraction, a major piece of British history beautifully preserved. The audio guide is superbly executed; it lets you walk through the chapels in your own pace. I am not a technical talent but it was very easy to navigate and also to select from the additional multimedia content. The English version is narrated by Jeremy Irons, the Hungarian version also uses well known voices from national TV which we found an advantage. The attendants are very helpful. It is difficult to understand why you are not allowed to take photos at all (not only the use of flash was prohibited).
