Checked into the HR Santa Clara for a two night stay (actually did an online checkin). Was assigned a stadium view room, so really no upgrade. Knew that balcony rooms were available so I prodded. Was assigned to a balcony on the 12th floor (original room was on 13). So, no proactive upgrade whatsoever. Flat out asked them what their upgrade policy is. Was told they try to assign high floor and quiet (so that must be their definition of "best available"). Absolutely no mention of better room category (I don't consider stadium view a category since those were just standard rooms before the stadium was built). They did mention that they had very few suites, but I think I was given a different number than the last time I asked
