Many people have done that in their TRs. Here is a link to mine from July/Aug 2014. This time my sister rented a car, last time and next time, I'll be taking a taxi. Probably taking the taxi from our resort (Pop Century) to Universal and coming home it depends on how we feel. We may take the taxi to DTD and browse around before taking a bus back to our resort, or just take the taxi straight to our resort. Saves $ to take the taxi to DTD but saves time to take the taxi all the way to the resort.

I didn't share all my Universal, Sea World or Busch Gardens pictures in my TR, but I did add them in various locations.
Universal:

And I can't believe I'd never done the SW day... off to do that now! I'll add the link after.
