I don't think you can get "to" DTD much after 12:30. Even though Pleasure Island closes at 2am, the last shows are really over about 12:30 and they pretty much go into a departure only mode.
So if you plan on closing down Jellyrolls (which is open till 2am also, right??) you are pretty much stuck with a taxi.
(For that reason above, Jellyrolls and Atlantic Dance will never see the crowds PI gets, cause there is no way to get "home".
If anyone else has a different experience, please speak up.
