We were there on Monday. It was originally supposed to close on Sunday, but they extended it for two weeks.
Took our daughter and two grandsons [5 yrs, and 17 months - baby was free admission] and everyone raved about it. Dinosaurs are awesome [41 of them] and are motion-sensor activated for movement and sounds. Open from 4 pm to 9 pm weekdays, not sure about weekends. Daughter said if they had it in NJ the admission would probably be $30 per person. The 5 yr old did the zipline and is still hyped about it.
I think regular admission is 300-350 pesos per person, but if you go to Jumbo on Luperon and buy 'anything', you'll get a coupon for 2 tickets for 175 pesos each attached to your receipt. [you have to buy them there in the store].
Definitely recommend it.
