Our case was a little special because we stayed at the Renaissance (literally across the street), and it was July 4th. Kinda like the people who stay at HRH when visiting IOA, you can't beat it. So we cleaned up, then went into SWF to see the fireworks, which had a real orchestra playing, wow.
If anything, I think the trip gets even better after doing DC because you're excited to have seen the dolphins. It's kinda like the pressure is off from wondering what's going to happen at DC, and now you can relax and celebrate. And you can go to the Key West area and feed the dolphins/stingrays, plus watch them swim behind the big glass wall underground. You have a greater appreciation for everything since you've gained some knowledge.
We did the rides, saw more shows, had a great time.
And then everyone Ooooos and Ahhhs when they see you walking with the DC badge around your neck. They all start asking questions about how it was. Of coarse, you'll chat it up and say it was the best.
