Not in a "I won't cope" way, more a freedom way 
Dc1 will still be home, but at (secondary) school mon-fri 8-4.15. I've got the week off work, and want to get myself organised to have a week which is both productive and fun
Dh and dc2 leave Sat 8am and get home the following Sat about 5pm.
All I can think so far is take dc1 for a night away on the first Saturday, and possibly try a bit of decorating.
Wwyd? How would you fill your week?
