Hide It
Bedrooms
The wonderful thing about a door is that you can close it. Simply shut off any areas that you didn't have time to tidy and particularly don't want anyone getting a peek at. Few guests will venture beyond a closed door to discover that you didn't make your bed.
Shoes and bags
Invest in a chest for the front hall. When guests are expected, you can throw the kids' shoes and knapsacks inside, shut the lid and any clutter is instantly out of sight.
Dishes
If you can't bear to leave a sink-full, transfer dishes to a laundry basket, cover with a tea towel and place them in an off-limits area like the laundry room or garage.
