Feel free to make your own decisions regarding who you want to see again. Sometimes friends come together and influence each others decisions on whom to pick. Remember this is your personal taste, not your friends.
Remember to always have a drink on hand, water or otherwise. You will be doing a lot of talking in a concentrated amount of time.
Try not to have the same conversation on every date, as this may get slightly boring and repetitive.
Remember to not only tell things about yourself, but to listen to what the other person has to say as well. This will help you make a more educated decision about whether you'd like to see them again or not, and it's also a common courtesy.
If you meet someone at the event whom you do not feel the chemistry with, but who you think might be a good friend, why not tell them right away that you will mark them as a "yes" as you would like to be in touch as friends? This way you both know where things stand and you might have gained a friend.
