Anything could work depending on how badly you want to do it, but SeaWorld is by-far the least insane option. I’d do that. Hollywood Studios is insane but doable. I wouldn’t do Universal if you don’t have an AP. No way…
If you do Hollywood Studios, just stack Lightning Lanes all day. This also assumes that your plane has good Wi-Fi. At 7am, get on there and grab probably Slinky if you care or Runaway Railway if you don’t once return times get into the afternoon. Right (and I mean right) at park open, buy an ILL for Rise. There is a standby line, but why do that to yourself? If a time doesn’t pop up, keep refreshing. Then 2 hours after the park opens you can reserve your next Lightning Lane. Keep doing this every 2 hours until you walk into Hollywood Studios with a stack of line skips for the afternoon.
Don’t go to Universal. You won’t get in much. I wouldn’t do Disney either, but I hate it less than I hate the Universal idea. My issue is, what if you buy your Lightning lanes and your ticket and your flight gets delayed by 4 hours? You can’t be spontaneous at-all with Disney. With SeaWorld you can just buy a ticket when you land and go.
