My Wife Has A Wake Up Guest Time! Leo and Rebecca Buzz Question

Leo and Rebecca Buzz Question - My Buddy and his family come into town and stay with us from time to time. Well, my wife hates the fact that they wake up at 6am every day they stay with us and go into our living room and kitchen and make all sorts of NOISE! So, she now has a GUEST WAKE UP TIME...and wants me to tell them that it's 8am! LOL...I laughed at her and said she is crazy, but she insist I let them know she doesn't want them up till then. Please TELL HER she's NUTS!! Thanks.
