Can I go on roller coasters two weeks after Septoplasty?

My friends are all going to the amusement park tomorrow and I very much wish to join them, but I did have a septoplasty exactly two weeks ago. The doctor said "no limitations any more" in my post-op about one week ago, but I'm worried that roller coasters might be an issue and he just did not mention that either because it was expected or because it's something that's not a common, everyday task like lifting objects or exercising.
