Do you really want to sell?
When people sign a P&S they start to feel attached to the home and can become clingy. When I purchased my house my mother in law rang the bell and asked the owner if she could look around. She did this without or knowledge and boy was I embarrassed
I can understand how frustrating this can be, especially since you may not be close to closing. As the other people have said, it can help if you look on the bright side. You are selling, and hopefully you have a good agent that negotiated well on your behalf. Right now you are in a contract and it may not be in your best interest to work on dissolving the contract no matter how annoying the buyers are.
Tell the family members who are watching the house that you are not comfortable with them doing it and make sure that your agent knows about it and can tell the buyers that they need to put a stop to it.
I wish you the best of luck and a speedy closing1
You have done the right thing by limiting the time in the P&S. But as others have said, to have an excited buyer is good. Spend your time packing and hopefully your as excited about your move.
You can't get out of the p&s, but you do have options if you don't want to sell it, they can be costly, time consuming and may not be fruitful either.
You don't have many options for getting.out of a signed P&S. If you want out for some reason other than annoying buyers, contact an attorney. Good luck.

In normal instances you should be fairly close to the closing date; so hopefully you won't have to put up with this much longer.
