I was without power three days due to Rita. However, counties with many trees were down a long time. It knocked down zillions of trees in the Sam Houston National Forest and towns/counties near it were without power that three weeks you are talking about.
After Ike and out of power for five days, when it came back on, it was glorious - celebration time. I also recall I was afraid it would go off again any minute - I didn't trust it to stay on. After a few hours, I thought maybe it will stay on. Sleeping that night was better than sleeping with a battery powered fan on the table next to the bed. However, without those battery fans, life would have been much harder.
We were evacuated for Ike as well but that was not as bad here. My SIL's parents lived in Houston and were w/out power for 2 weeks after Ike.
As bad as 98 degrees/humidity is without AC, I guess it beats 32 degrees without heat.
