The Sea lion experience is within the Aqua Show Park and although you don't have to pay to enter the park (you can turn up and be escorted to the Sea Lions and back out again) it makes sense to make a day of it and do the water slides, rides etc as well.
Cost 49 Euro for one child to 'experience' the sea lions. Our daughter was one of 12 or so people in the group.
Like many places, there is the usual obsession with taking photographs which you can purchase afterwards. In fact the whole Aqua Show resort have taken this to whole new level with photographers and various 'wild' animals at every turn. So my only criticism would be that they are careful to make sure you can't get as goo a photo of your own child with their animal as they do.
But the staff were very friendly, helpful, humorous and participants do get the full 45 minutes allocated and probably a bit more, albeit the two sea lions must share their time with the 12+ participants.
A warning: the water is kept at 5 degrees so be prepared to get a little chilly or bring some extra layers. There's also little or no shade around the sea lion pool so if you're already overdone the sun, bring something to cover up with.
