2. Get cozy during National Lazy Mom’s Day

September 6th is National Lazy Mom’s Day…That sounds like a great reason to get a few of our fellow moms together for a relaxing party. Hit the spa, have a brunch party, and watch some movies in a private screening room with no kids allowed!

Did you know that Peerspace has venues where you can enjoy a relaxing time with your besties? If quiet times indoors are a part of your National Lazy Mom celebration, think about booking a coffee shop through us!

3. Have a wildlife safari party

Wildlife Day is September 4th. Bring together other nature lovers for a wildlife-themed party, like whales, sharks, or a wilderness safari! You can even dress the part, with khaki shorts and sun hats. Decorate the space with some balloon animals and have a fundraising event to support the charity of your choosing! Safari parties for kids’ birthdays should include safari-themed games as well!

September is that time of year when summer vacation is coming to an end and the kids are headed back to school. Throw them one last party before it’s time to buckle down and study! A back-to-school party is a fun way to get their friends together with snacks, games, and other activities. Set up a photo booth for some end-of-summer pics together and encourage them to share what they’ve been up to with a show-and-tell event.

5. Make some fall crafts together

Autumn is the perfect time to head indoors and make some crafts! Why not have a DIY crafts party using autumn leaves, decorative gourds, straw, and other autumn elements? Make some leaf prints, dried flower arrangements, or paint some pottery together.

6. Celebrate video games day with a gamer party

Did you know that Video Games Day is September 12th? Have everyone bring over their laptop or PC for some group gaming! Play Fortnite, League of Legends, Wow, or another multiplayer online game together in a space set up with snack tables, drinks, and chairs. A great video game party should be set in a game-themed space, like an arcade that you can book and decorate through Peerspace. For example, if Pokemon is the game of choice then use Pikachu in the decor, serve Pokeball-shaped cupcakes, and so on!

10. Celebrate World Tourism Day with an international party

You don’t need to pick up plane tickets to celebrate World Tourism Day on September 27th. Not when you can have a party right in your own city!

13. Throw a hot beverage party

The cooling nights of autumn’s approach means it’s time to serve warm drinks during a September party!

19. Get outdoors with a glamping party

Now is the time to get outdoors and appreciate the changing of the seasons! Watch the autumn leaves drop and enjoy cooling nights with your friends. But you don’t have to sleep in a dirty tent.
