Thinking about doing a Universal Studios/Sea World trip in January. I have some questions about Sea World. How much of the park is Roller coasters? I know Universal has a good amount of them and I'm not a big Roller coaster fan (except for the Mummy must be the dark ride feel). How crowded is Sea World on a MLK Day weekend? Is it busier than other times in January or closer to July? Ready to do a non-Disney Trip, but want to get good value out of the parks I choose.
