As DSLRuser states, the final hour of the day is considered the golden hour for its great warm colors. I personally believe the first hour of the day is just as golden, but you probably won't want to do a photo session that early.
You can get really good light from 2 hours prior to sunset until dark. But that last hour is generally very special.
I'm not familiar with the N-S-E-W configuration of the hotels. In general you will want to position yourself with the sun hitting the faces of the subjects, or coming in from a slight angle.
