Notice the total at the top right is not actually $579.408, but $595.04, a difference never explained in the UI.

Based on actual totals, the effective discount is even lower:
2 - 595.04 / 319.88 = 14%

For 2 adults + 1 child the "40% off for children" is an even more meager 5.66%:
$319.88 * 3 = $959.64
$362.13 * 2.6 = $941.538
3 - 941.538 / 319.88 = 5.66%

Actually, it's not even that… [3/5]
