Room darkening shades
Seriously, it's the only way we got through it last year! And ITA with the pp who said that they do tend to get up earlier. For dd, this was havoc because she was going to bed late and getting up early, and she was an absolute bear all day long! When we got the shades (and I mean the heavy duty ones from like Home Depot or something, not the flimsy ones from Wal-Mart... it's well worth the extra $$) she finally started going to bed before the sun, and we had some peace again.
This year, I've already got the shades going, though I might have to velcro them to the wall or something so that no light peeks in at bedtime. I go to bed pretty early myself, so I feel you on the no time to yourself dilemma!
