Montu has ranked as Florida's best roller coaster since it was built 1996. It's my favorite at Busch Gardens and features 7 inversions while gliding in and out of trenches that fit in with the Egyptian theme.
The queue line was pretty long the last time I rode it. I had a quick queue pass so I'm not completely sure, but I'd estimate it was a 45 minute wait. Keep in mind that was on a very busy day.
The ride itself is smooth, fast, and intense. Don't ever skip it while you're at Busch Gardens.
