Keep it as simple as you like and serve breakfast food that everyone will enjoy. Waffle or pancake-making bars become an activity as opposed to having food laid out. Have bowls of yummy add-ins like Resees pieces, M & M's, fresh fruit, nuts, peanut butter, different jellies, flavored syrups, and of course whipped cream. If you are thinking about making waffles, they now have a spray can waffle batter so everyone can make their own with a counter flip waffle iron.
Spin these many ways based on age ranges or guests invited. For kids, this can be an afternoon party where your kids invite their friends and watch cartoons in front of the TV, or they can decorate pillow covers to take home. Purchase puff paints or fabric painting kits to place on the kitchen table, but make sure to cover it well. Teens will like this idea for an early evening party where they can tell ghost stories, play board games, and, if you have the ability, make S'mores. An adult-only get-together can include a breakfast bar with some mimosas and socializing. For family reunions, include games like Pictionary with a large drawing pad on an easel so everyone in the room can see.
A fun game for guest of all ages that requires little prior planning is the wink and murder game where each player pulls a slip of paper from a stocking cap and some papers are blank, and one paper identifies the player as the killer. Throughout the party, the "killer" winks at his/her victims, and they have to fake their death a few minutes later and far away from the actual killer. Guest can guess who they think the killer is before they are wink-killed. If they guess wrong, they have to fake their death. (The player has to whisper the question "are you the killer?" into the person they suspect's ear for a yes or no reply. If it is yes, they are the winner, and if it is no, they must fake their death).
When we played this for our family reunion, my father-in-law turned out to be the killer, and absolutely no one suspected him as he had a bit of difficulty getting around and is pretty quiet, so he just waited for his victims to come to say hello. One of my nieces even decided to up her game on her faked death by painting herself with horror makeup and fake blood. This game has been around for a while and has many different rules and names. I am not sure where it originated, but it is a brilliant activity.
Looking for Pajama ideas? We bought ours at Jumpin jammerz because they had camouflage footed ones for the guys. Of course, you can find cute pajamas anywhere.
