Yes, that's what I'd do. You come out pretty much even on the 3rd ride in the 24 hours, and if you're staying for a couple of days you might as well.
The only bus you could use your Opus on upon arrival is the 204/211 combo to get downtown. Depending on your arrival time this may not add all
that much time to your trip (the 211 uses the same route as the 747 to get downtown), but depending on where you're going it will probably take a Metro ride as well.
