This attraction was so much more than I expected. Book tickets online in advance to save a few pounds and avoid the long main queue. You still must either print or collect the tickets, there isn't a e-ticket option it seems. We had a tour from a beefeater at the beginning who provided the history of the various buildings and towers and who recommended which areas were a must-see. There is so much to see you'd want at least 2 hours in my opinion. The tower also houses the crown jewels which are spectacular. Well worth a visit.
