Bachelor / bachelorette party need not be synonymous with a disreputable male/female circle of friends that invites dancers or strippers to entertain them until dawn. Therefore, girls and boys relax and allow your future life partner to spend their last free night with the taste of adrenaline. That they spend adrenaline-filled, crazy and fun night in untouched nature, on a picnic area near a river, or at a weekend house. They will come back to you tomorrow anyway!
And do not forget that this rafting adventure symbolizes your decision to leave a single life and start a married life, which means you should celebrate with style.
