Need opinions!

We're having a gender reveal party in 2 weeks. My husband and I want to find out the sex in the doctors office, just us two. We feel that it's a really special moment for us to share. I know for a fact my husband won't have the same emotional reaction in front of 20+ people that he would with just me. We want to tell our families the big news at the party, but have had a few people who don't understand why we aren't waiting to find out with everyone else. My reasons are justified..right?!
