I just saw the above artist concept of Universal Studios on-site hotel,Sapphire Falls. Maybe it's just my first impression, but, I was immediately reminded of Aulani's grand entrance, as well as obvious design elements from Disney's Polynesian Village.
I guess imitation is a sincere form of flattery, but, 'c'mon man!'
I'm sure there are many other examples of intellectual property being lifted by the competition.
