Amusement parks

I am currently 10w4d, not showing, and for the most part, feeling good. I will going on a pre planned group trip to a beach boardwalk amusement park. I know pregnant ladies are no supposed to go on roller coasters, but what about smaller rides and roller coasters? This isn't a huge theme park with big drops and loop de loops. The biggest are a big classic wooden roller coaster and a splash mountain kind of log ride. Would it be okay for me to go on these? I'm still early on in this pregnancy and only very few people know, so it will be hard to hide by not going on the rides with everyone. They know I like roller coasters.
