Almost dumb. I asked this in the Hyatt thread:Was talking to my son about it. He wanted to know if I was stupid. Didn't answer that one.
He asked "do you know how many SUB you can get for the spend you are going to do"?
Case closed!!! 
I'd say $100-200 per stay value
Free parking on award nights is $40+
Free breakfast especially if you aren't kosher / cy worth $30-45 pp
Upgrades .. infinite value
Nights achieved - 30 nights cat 1-4 $150+
40 nights $100 gc
60 nights cat 1-7 $300?
Figure, on 30 nights actual stay, 30 nights spend ($75,000)
You'd have 75k min points (lots of bonus spend offers)
3 cat 1-4 $450
1 cat 1-7 $300
1 gc $100
That's $850 plus $3000 built in value on 30 nights... So $3850 value
