Weight / Fat loss

I'm going to NYC for two weeks. Will be without bike but my aunt (who I'm staying with) has a 24 hour gym in her building.

I know some of you people go to the gym, any suggestions for a good 1-hour morning workout? Should I just do 1 hour on the bike machine to replace my usual commute or is doing 15 minutes on four different machines better?

DFPs looks good. I'd find that too intense for the morning. I'd probably do cycle - row - run, with some core work thrown in*.

(*this is a lie, I'd probably do weights. I'm somewhat addicted)
