It's a Fairfield Inn, so I don't think you're out much regardless. I don't understand the lack of hot water, unless the hotel uses electric for it's heaters. That, quite honestly, is the real complaint. The partial power outage was during the day, when you admittedly weren't going to be there much. It's spring, so I don't think the AC issue is a biggie.

As far as compensation, 5,000 points would be the minimum, or a comp of one night's stay. If it was winter or the middle of summer, and you were cranking the heat or AC at night and it you lost power, that's a big deal. Or, if you're there for work, and internet access is down for an extended period. As is, not having AC for a few hours in the morning in springtime, and missing out on a free waffle is not a massive loss. But, you have to complain while there.
