These blocks are worth choosing before blocks 5 and 11 if you prefer a distant but more central view. Legroom is adequate in all seats. Dancing in the aisles is not permitted at concerts, as the stands vibrate. This was the infamous stand that collapsed a few years ago. These are divided into two parts, the lower tier called the Balcony, with portable seats, and the upper tier, rising directly behind, called the Gallery with fixed seats.
All blocks have double rows of metal bars in front as well as a gangway.
The view is not badly affected but theatremonkey advises row D back in all blocks before choosing C then B then A in that order. Blocks 20 and 29 are closest to the stage, then 21 and 28. All offer a good view, preferable to the centre arena below. Blocks 22 and 27 offer a fair view. Blocks 23 and 26 are at an angle to the stage with a fair view, worth taking before blocks 24 and 25 which are facing the stage but further from it.
