The website has these descriptions for kids' dining in specialty restaurants. I reserved dinner at Pinnacle with my 12-year-old but was charged full price, even though the website says children 12 and under are half price and the reservation system supposedly knows her age.
What's also frustrating to me, from following the boards in the past few months, is all of these policies that aren't applied universally across all ships. Milkshakes in beverage package or not? Elite beverage now capped at 15 total, including non-alcoholic drinks, or not? Does the teens club age range start at 12 or 13 years old?
Sorry for the tangent. We sail on the 24th (on Zaandam, though) so I would also be interested in answers from experienced cruisers.
