I posted something similar in the Ziva Cancun thread, but am seeing the same thing across all the Hyatt all inclusive properties. Hoping someone can shed some light on this.

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 standard rooms for 25K points, and standard 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.
