I enjoy going to DCA a couple times a week. Of course, we usually go with my neice, and she likes the "Bug's Land" area there. Also, I haven't been to WDW in over 20 years, so some of the stuff there is "new" for me. I haven't been to the Tower of Terror in Florida, so this one is all I know.
All that said, I still like DCA. It's not near as good as the main park, but it's usually less crowded, the food is good, and the atmosphere is much more relaxed.
I'll tell you about my "first impression" of the park, the first time I went back near opening. I thought it was cool because it was new, but remember thinking, that if I paid "full price" to get in to this park, I'd be ed. I can't imagine someone paying for a one-day, full price, non-park hopper ticket to DCA. It's just not enough stuff. Compared to all the things you can do in Disneyland, DCA just doesn't feel big enough.
I really like California Screaming, though I do like most coasters. Very smooth ride, one loop. You might be able to handle it.
I'm not sure what the "Soaring" ride is in Florida, but "Soaring Over California" is really nice. At opening, I thought it was the best ride in the park.
Overall, I like the park, and go there for a few hours a week on our annual passes. It'll be VERY interesting to hear your thoughts as a visitor for the first time when you get back.
As a last note, the tortillas are REALLY good. I know it's funny that people keep mentioning it, but because they're freshly made RIGHT THERE, they're different than the tortillas you get in a store. My neice is only like 16 months old, and she's so cute they usually give her a whole one. She loves them too! Also, my sister went on her birthday, and had a birthday pin on, and they gave her a whole bag! Tortilla heaven! I do love bread and most bread-like things though, so I'm biased.
