So here is my question. My fiance and I got engaged about 3 weeks ago. We have been together for 5 and a half years, so we want to have a somewhat quick wedding. I have had my heart set on having the reception at a certain place since I can remember! So as soon as we got engaged, I emailed the lady to see what dates they have open for next summer (we are having the ceremony on the beach). So the three dates she gave me were three weekends right in a row. The middle weekend, my cousin is getting married about three hours away. So we decided to choose the 1st of the three weekends. I sent my cousin a message making sure it was ok, but to my surprise, when she responded, she wasn't too thrilled. We can't do it the 3rd because I am a teacher and school will start around that time. My question is, was I wrong to choose that date right before hers? We have no other options, and I wouldn't be happy doing it anywhere else

I don't want to wait until the next summer, because that's just too long of an engagement.
Thanks ladies
