My wife is a globalist and we are considering booking our first Ziva stay on points with our 14 year-old son. I'm confused by the way it's pricing out. When I search for two adults, I see plenty of dates with both standard rooms for 25K points, and pyramid suites available (we'd use a TSU for this stay). When I add the third guest (age 14), the points rate for a standard room jumps to 50K, and it says that rate is for two additional guests. I was expecting the rate for three guests to be 37.5K points per night. Out of curiosity, I lowered the age on the third guest to something under 13, and it shows the 37.5K rate for three guests. I understand 13 and up is considered an adult, but even the standard rooms list a max capacity of up to four adults. What am I missing here? Obviously we could ask our concierge to do the booking and upgrade, but want to make sure I understand the occupancy rules/third guest pricing first.
