My question applies to Universal, Aquatica, SW and Busch Gardens, since I'll be visiting all of them. I'm so used to having free parking at WDW so now the thought of paying 5 separate times is disconcerting. I always find free parking at the theme parks in Southern CA, and was wondering if there's anywhere within walking distance to do so for any of these parks. I don't mind walking, as long as it's not over major freeways or areas where there's no sidewalks/etc. If anyone has any advice I'd be most appreciate. Thanks!
