It looks like this property has a promotion on its website where kids can stay free. The promo code is 95798 and can be seen here:
https://puertovallarta.ziva.hyatt.co...60948024&code=
The terms say: Offer valid for bookings made December 20, 2017 through February 7, 2018 for stays from April 12, 2018 through December 20, 2018 at Hyatt Ziva Puerto Vallarta. Blackout dates: May 1 – May 31 and July 22 – August 16, 2018. A 3-night minimum stay is required. A limited number of rooms are allocated to this offer; reservations subject to availability. Offer not valid with groups, conventions, other promotional offers, tour packages or special rate programs. Additional charges may apply for additional guests or room type upgrades.
However, I've search for many dates and it looks like there are never any rooms available with this promotion.
Is there any way to search on Hyatt for flexible dates to see when they have any dates with this promo?
