The best part about a birthday is having your favorite people there to celebrate it with you.
1. For a fun weekend adventure trip, plan on inviting 3 to 6 other friends, for a total of 5-8 people including you and a significant other.
This will give you enough people to make it seem like a true celebration, without making the process of planning too daunting.
2. Once the group number climbs past ten, the chances of finding a weekend that coordinates with everyone's schedule is nearly impossible, which is why we recommend keeping it simple and sticking to eight or less total campers.
