Buy the city pass, it's definitely well worth it
It depends, if you do a CityPass you save about 40%. Their price are on their website
online
Cheaper on line
It depends adults and child vary. Buy online it's cheaper than at the gate. We payed 92 for 2 adults at the gate. They also have a huge discount if you buy after 4.
