I believe there is this Harry Potter themed Roller Coaster in Disney World,Florida. It's rather fast maybe you should try it out c:
The worst ones are: Apocalypse - Drayton Manor Air - Alton Towers Oblivion - Alton Towers The Smiler - Alton Towers Nemesis - Alton Towers idk the name - Movie world, in gold coast, Australia, (like magical, it was in 2013 on the 3rd of January I think, when did u go magical?)
I've been on one rollercoaster in my entire life. The one at Melbourne, Luna park. Fun, but slow and boring :/
I've been on the fastest coaster in the world which is in Abu Dhabi, UAE. It goes 260kmph, its AMAZING :O I went on it 6 times :P
My first rollercoaster was a small wooden one that goes trough a gigantic apple, everyone was screaming cuz i almost fell out. I've also been on a rollercoaster in Efteling, first i didnt want to sit in it so i was crying when i wasnt even in the rollercoaster... at the end i did go in it and everyone was screaming WAAAAAAAA en i was screaming YEAAAAAH AGAIN AGAIN AGAIN, i was 9.. A roller coaster where you are really close to water and when you sit 1 time in the roller coaster you ride 5 rounds, i almost puked on my friends And other random roller coasters and im maybe going in the fastest roller coaster in the world when im going to vacation! ^-^ yay!
My first rollercoaster was the "Krake" in Heide Park Soltau in Germany WOOOOHOOO Awsome!!! I re-eated a whole meal. xD
Bizarro in six flags all the way in Jackson, New Jersey. I swear, the fire contained in this ride might touch you. I got burnt.
