Put me down for SFMW too, a much better overall park than PGA could ever hope to be. PGA may have more coasters, but with the exception of Stealth and Top Gun, all the other rides suck, and are all low capacity, so you wait an hour for everything, even on weekdays. Stealth, although a great ride, is another low capicty coaster, has minimun 2hr lines from the minute the chain drops. Plus the park is ugly as hell with all the trees ripped out and the original Marriott theming painted over in multi-colored neon for Paramount crap. Feels more like your at a ugly tacky carnival than a theme park.
Now SFMW, sure they only have 5 coasters(people forget about Cobra), but remember, they just started adding rides 3yrs ago. And already the park is way more beautiful and amazing than PGA. And as stated, Medusa and Roar pack a one-two punch much better than anything at PGA. Then all the latest in flat rides are here, all beautifully themed, you gotta do the Huss Frisbee(Tazmanian Devil), that ride is such a blast! Then all the animal attractions, shows, and exhibits are all top notch and facinating. Many people say SFMW reminds them of BGT, it's that well done.
If you want to just ride coasters(most of them lame)and nothing else, go to PGA. But if you want an overall great park experience with 2 of the best coasters out here, plus the best ride package in the area, go to SFMW, you'll have a great time. Just my opinion :)
