Ok, so not necessarily a battle of two characters from the two series (though I do know who would win), but which series do you think draws more fans to its destinations? Well, if you include the Harry Potter World at Universal Studios in Orlando, FL (searching for discount hotels in Orlando, FL???), it is the Harry Potter series in a landslide. However, take that out of the equation, as it is not part of the original filming scenes and the winner appears to be the Twilight series. There are still a number of tours in Portland and Washington State for the movies.
I just read recently, however, that there will be a focus on some of the Harry Potter scenes and Hogwarts, just outside of London. A behind the scenes tour will be opening up just in time for the Summer Olympics in 2012.
