Not really. Think of what they did with Diagon Alley in the space of one attraction. If they play it smart they could make an amazing, fully fleshed out land for HTTYD in the Lost Continent. I get what you're saying though, but HTTYD fits in IoA and I still think Christmas land is a bad idea. Integrate those characters at Christmas time definitely, but a year round Rudolph ride, headlining one of the islands in Islands of Adventure? Yikes. Terrible idea in my opinion.
