Gardaland is much more of a family park, so it fits in quite well with their other rides. Therefore, no, I'd guess probably not.
I understand what they're trying to do with Thorpe, but I'm not sure its that smart of a decision, imo. The amount of times I've been there and heard families with crying children complaining that they've paid a fortune to get in, and there's nothing for them to do. The trouble is, unless you're all adults or older teenagers on your own there's no point in going to Thorpe. A lot of families will have a younger child and a teenager. If they go to Thorpe, ok, the teenager will enjoy it, but the younger child will be bored and upset for the day. The other problem with this strategy is the atmosphere it creates in the park. I have to say, it actually wasn't THAT bad on Monday, but I'd say that was the exception rather than the rule. Having mainly families there makes it a more pleasant place for everything.
In my opinion, the only way they can really justify this is making it free entry for anyone under what, 1.2m?
