We are leaving this Wednesday and plan to only have 1 day (Friday) at universal before leaving on Disney Magic on Saturday. But can't decide which park? Have to DS ages 4 (42inches) & 9. Since 4yrDS can do everything at Universal Studios thought to go there. But he really really wants to see Spiderman! 9yr DS of course wants to do to both. We are staying at RP on Thurs nite, so with Express line thought we could get thru both parks. So is there a 1 day park hopper? Or do you just have to pay for both separately? Speedy replies would be greatly appreciated. THANKS
