I started reading through this thread to get my answer and then realized it was 334 pages long - I kind of need an answer by today. Sorry if this has been answered before - wiki isn't 100% clear on this.
I am a Diamond member and my friend wants to book a hotel (Regency Scottsdale) - Can I book for him using cash, use a suite upgrade, and put him as second guest? What are the risks?
TIA
