Oops-that post to myself was supposed to go to you-I called hubby and told him not to leave the city without going to the bank unless he plans to put dinner on plastic.
i am sure it will be fine once they get there and you will enjoy their stay and they will love the house and think everything looks fantastic, but i am just like you and i don't like surprise guests, i don't like changes of plan and i always get worked up over houseguests, but in the end it is just me being nutty for no reason. you will have fun, and tomorrow you can shop and plan. family should be easy enough to please, shouldn't they?
