Mocktail Party
Although the legal drinking age isn’t until 21 in the United States, you can still celebrate with a fun mocktail party! Come prepared with a menu of popular mocktails for the guests to try. Or, have each guest come with their own recipe to prepare. My Virgin Blue Lagoon Mocktail Recipe and Aperol Spritz Mocktail are two non-alcoholic drinks teens will love!
Casino Party
Although casinos are reserved for the 21+ crowd only, you can still celebrate adulthood with a glitzy casino party! (Betting not required!)
Have your guests dress up in their best casino wear and get ready to play fun games such as poker, black jack or roulette. If you don’t already have the games at home, you purchase smaller versions of the game on Amazon.
If you can afford it, hire a caterer to serve a few appetizers passed around on plates!
Club Night
One of the best parts about turning 18? Finally being old enough to get into that nightclub that you’ve had your eye on! While many nightclubs are reserved for the 21+ crew only, there are still plenty that admit guests aged 18 and up. Check ahead of time to see whether the club offers special VIP sections or packages for birthday guests and their friends.
Decade Party
What better way to celebrate an 18th birthday party than to celebrate the year that the birthday guy or gal was born? With this fun theme party, have guests arrive dressed in the style of clothing that was most popular during that decade. The party decorations, games and music can also reflect the popular items during that decade as well. For sweet and fun touch, visit Old Time Candy or Just Candy to buy old-fashioned candy from that decade.OR throw it back and host a 90's theme party!
Tattoo Day
Another one of the rights of passage for turning 18 is being able to get a first tattoo or body piercing without a parent’s permission! If getting inked has been something of interest, use your special day to make that trip. Make the day even more special by inviting along a friend or family member to get a tattoo as well! Matching tattoos, anyone?
Party Bus or Limo
