Update: Interview went really well. the HVAC training I am finishing up I think is going to set me apart from from any other applicants. It seems there is a hole there to fill as far as that is concerned. I should know something by the end of the year.
Ive done some service calls at that renassance, for refrigeration. It was all water cooled. I also know someone who worked there as an engineer, and left after a couple months because of the low pay. The marriotts also started hiring their own "hvac cluster techs" to service multiple hotels.
