Even if you don't like harry potter or even care about it I can tell you the Harry Potter area was about the coolest thing I have ever seen. The themeing alone is amazing and the main ride is better than any Disney ride I have ever been on. I LOVE Disney don't get me wrong but the themeing of Islands of Adventure is amazing. I think you would like that place better too because they have different areas that are themed. So they have a marvel area that probably your boys would like and then an area with like popeye and Dudley Do Right and of course the Harry Potter Area and the twins would LOVE the Dr. Seuss area. So there is more for everyone and the rides and themeing are AMAZING. I agree the Hollywood one does nothing for me and it is fine every 5 or so years when there is nothing else to do and mom and I actually go there sometimes and just go to city walk but I am not even that excited about going next month. We only added it in since we can't go to
Disneyland and wanted to do something the girls would like.
But the Florida version is amazing and I think you would like it better if you ever had a chance to go. And of course going at a downtime make a huge difference too.
