My best recommendation is to buy on the official website. There are discounts sometimes for various parks. Do not fall into unofficial pages that often require you to attend talks that make you waste your time
On the online page
On the universal page are the prices and discounts according to the number of days or seasons
App
on the Universal page they indicate all the possible discounts to which you can apply
If you buy tickets for both parks, you may get a 20% discount, check the page.
You can look on the website directly from the parks!!
