Does anyone have experience in booking Hilton stays through AA Vacations? (the packages through American Airlines). You choose the hotel you want to stay at and they give you a package deal for the flights and hotel at considerable savings. To make the best decision, I want to make sure I understand the difference as a Hilton diamond member. I'm guessing I probably won't get stay or night credit. But does anyone know for sure? Would I still get the executive floor upgrade and access to the executive lounge? What about points for incidentals like room service, etc? Thanks for any info!
