I don't know if people are looking at this board anymore. I think I tried for at least two hours to deliver the package to SinWave Nightclub. The problem? I tried multiple times to park and get there and never managed it. I saw two places to park. One small, one large. Looks like playthroughs are showing that the large one gets you there. Except in MINE it doesn't. I walked around that part of the city hundreds of times. I give up.
