I wasn't aware that you saved 5% throughout the park with the Discover card---I just thought it was admission.
A Ferris wheel would make a nice attraction at SFMM. Their old Galaxy (where Buccaneer and Swashbuckler are now) was a good ride, though it often didn't run because it was troublesome. A good drop tower makes sense to add because it would fall in line with the thrill factor at the park.
However, because SFMM has become known for its coaster collection, I can't see them adding many non-coaster attractions in the near future. Ferris wheels are slow loading, so they're not going to get the capacity.
I hope Bonnie walks through the park on occasion. The only thing is, though, that oftentimes Jay or Neal would greet people and ask how their day was going only to get little or no answer. Many guests weren't sure what to say next because they weren't used to having people in a shirt and tie greeting them.
My Honda will run ringz around your Saturn.
