Affiliate Marketing Secrets

Okay so my birthday is coming up next month (Feb 23rd). I want to have a party in March, when it’s warmer, and the winter sports season has ended (most of us are athletes, and I don’t want sports to affiliate with anything).
But the problem is, I don’t know what to do…
I was thinking of having a party bus. But the problem is I made the list, and I don’t have that many boys.. it’s a list of 30 people. I was going to ask people to invite people. Not only that, but some of my friends aren’t “party people” and I don’t want them to just sit down there awkward…
What to do? Or what should I do? I really want a party bus though…
