I think you'll have a great time on this Orlando area trip. Whatever parks you choose, you'll have some fun coasters to try. There is a lot of variety, and one of the other posters gave you a great list that I pretty much agree with. I'd rank the Manta, though, the new one at Sea World quite a bit higher on the list. I thought riding on your stomach and the sensation you get at the beginning of the ride when they position you to go on a big loop backwards on your stomach was awesome.
This is probably off topic, but I'm a roller coaster enthusiast myself and couldn't resist mentioning my favorite place to go for a roller coaster fix (Cedar Point) in Sandusky, OH (
http://www.cedarpoint.com/index.cfm). They have 17 coasters in all, tons of great ones there. My all time favorite two are at this park: the Top Thrill Dragster and the Millennium Force. I like these better than any of the coasters in Orlando or Tampa. I'm big on super fast and smooth (that's my favorite kind of coaster). The Shrikra at Busch in Tampa sort of fits in the fast and smooth category, and I liked that one a lot, and would rank it just below these two at Cedar Point when ranking my personal favorites. I'm just mentioning this in case you might do a future trip to this area of the US sometime. Cedar Point is a seasonal park, though. I've found early June midweek the best time to go. Sometimes people when doing a trip here (if it's more than a mini trip) will do three nights at Cedar Point (for two days at the park), three night at Niagra Falls, and maybe do a mini trip to Toronto, Canada too. And coaster enthusiasts sometimes will check out Kings Island, also in Ohio (another amusement park owned by Cedar Fair) a few hours away from Cedar Point as part of their trip. They get a Cedar Fair season pass and hit these each.
Happy travels. Post a report after your trip letting us know what coasters you did and what your favorites were.
