Very crowded but a must-see for sure. If you come during the day especially during the summer or another holiday, expect it to be packed with tourists. As such, I wouldn't recommend making many purchases, as everything is overpriced.
Definitely take a tour with the yeomen, they are hilarious. The Crown Jewels exhibit is stunning and while the line may look intimidating at times, it moves quickly.
