Need your opinions - do you think I should go

I am suppose to leave Friday afternoon and come back Saturday from a sorority weekend. I am an active alum and there is a chapter opening in NJ and they asked my Alum group as well as the initiated collegiates to participate. I agreed to be there.

Last night I get an email from the Alumni Advisor (who is a friend of mine but also mad at me because I asked another sister to be in my wedding and not her) for the collegiates asking me and another girl if we would mind driving because her car is over its milage and she dont want to get a rental car and the other girls car wont make it. She also lives in Long Island. I told her I cant because FI needs the car for work. We havent heard back from the other girl. I know the other girl, she wont even drive to Queens so asking her to drive 3 hours to NJ is out of the question.

The advisor also told me to be at her house at 1pm. I asked her if I could carpool with another alum because she lives 5 minutes from me and it would be a lot easier for me to meet up with the other girl as it will be completely impossible for me to go with her. She told me its easier the way its set up (I have no idea how. The 3 girls live in Long Island and I have to travel out to them, where I have alums that are 5 minutes from me) I am starting to change my mind about going.

What do you girls think?? I spoke to FI and he said I know you, you will dwell over this and you shouldnt. If she wants to be uncooperative its not worth it to you dont go. I am starting to agree
