I really like the idea of having this somewhere - coasters, or something to write at the tables.
Bridal Shower Game. Have guest write vows for the couple to read in a mock ceremony later in the evening. Boys write vows for the Bride to vow to Groom and girls write Grooms vows to Bride. Hilarious Game / activity for wedding shower or Engagement Party.
ACTIVITY | A Kissing Menu for the Bride and Groom - Clinking glasses all night long to see the bride and groom exchange a couple of pecks can get a bit trite. Why not jazz it up a bit with a kissing menu? This way your guests will need to work together (and have some fun) before you reward them with a smooch.
