Ice Cream Social – Cool off in the summer heat with a fab ice cream party. Delight your guests with big scoops of traditional favorites (including lactose-free options) and stock the table with yummy candy and fruit toppings.
Luau - Greet each guest with a lei and signature drink. Pass out hula hoops, turn up the Hawaiian music and get in line for the limbo.
Beach Party - Whether you are chilling by the sand or relaxing in a high rise, a beach party is a fun theme and easy to pull together. Decorate with blow up beach balls and sand buckets and keep your favorite party drinks stocked in the cooler. Did someone say water balloons?
Tea Party - Pinkies up! Don your fancy headwear and serve iced tea, finger sandwiches and beautiful desserts on fancy plates. Move tables outside under string lights or entertain inside when it gets unbearably hot.
Flamingo - Are you ready to flamingle? Get guests in the party mood by staking out colorful birds throughout your home and yard. Serve pink drinks and let guests take a shot at a pinata.
Backyard Games - Create the ultimate recess retreat with games like cornhole, giant Jenga, kick the can and disc golf. Keep the food fare simple with an order of pizzas and serve classic soft drinks or lemonade.
Camp Time - You don’t have to leave the comfort of your backyard to enjoy the great outdoors. Set chairs around a fire pit and roast hot dogs and marshmallows, make up songs and tell your best ghost story.
Wine Tasting – Sample the best of the wine country without leaving home. Ask each guest to bring a bottle of their favorite vino and conceal the label. Host a blind tasting and see which bottle takes top spot. Have fun creating your own charcuterie boards for the win.
Classic Picnic - Ask guests to pack a picnic or serve a spread with delicious grab and go options. Set tables or blankets around the lawn and enjoy a game of croquet or bocce ball.
Jaws Movie Night - Watch this classic movie outside or turn down the lights to set the mood for an inside viewing. Serve popcorn, boxes of candy and sodas.
Potluck Party - Simple and budget friendly, a potluck is the perfect spur of the moment, anytime get together. Ask guests to bring a dish to share and their favorite board game.
Summer Olympics - Celebrate Paris 2024 with a battle to the podium. Assign guests a country to represent and compete in silly games like wheelbarrow relays, an egg toss and musical chairs.
Y.O.M - A “bring your own meat” party is quick and easy to throw together. Ask guests to bring whatever they would like to fire up on the grill and a side or dessert to share.
Great Gatsby - The perfect excuse to glam up summer! A roaring 1920s Gatsby party calls for cool cocktails, hot jazz and a night of cutting the rug.
Decade Party - Choose your favorite decade or ask guests to come dressed in their favorite 60s, 70s, 80s, 90s or 2000s attire. Create a playlist with the biggest summer hits from the era.
White Party - Baby it’s hot outside - go cool and sophisticated with a classic white party. Started in the 1970s, the rules are simple - decorate in all white, wear all white, serve all white - you get the picture.
Low Country Boil This crowd favorite is the perfect way to feed a large group with tasty fresh ingredients. Adjust the recipe based on the number of people on your guest list and dive into the ultimate summer feast!
Casino Night - Place your bet on a memorable night with a cool casino theme. Let guests take turns being dealers and set up games like blackjack, craps, and roulette (add bingo for the kids). Prepare a buffet-style spread with finger foods so hungry players can dig in.
Pool Party When you’re hanging out poolside, you don’t need much to make it a party. Throw some fun floats in the pool for décor, play some games, serve colorful drinks and fire up the grill.
Margaritaville - Calling all Parrot Heads. A Buffett-infused evening is a fantastic way to celebrate summer with a Key West vibe. Set up a margarita bar, serve seafood treats and key lime pie and play music from your favorite Son of a Sailor.
Happy Holidays - This is a fun theme to plop right in the middle of a summer heatwave. Offer cool versions of holiday favorites like peppermint martinis, frozen hot chocolate or a cheeseball in the shape of a snowman. Finish with a summer gift swap.
