Not telling anyone

Your expecting twins until the gender reveal party. My husband and I like keeping our personal life pretty personal and when we like to tell people about our personal life we like to shock everyone. We found out were having twins but we dont want to tell our family until our gender reveal. We kept my pregnancy a secret for awhile before telling family or friends so we thought we would surprise them one more time and not tell them until the gender reveal. What does everyone else think about this and was it hard for you to hide from everyone your having twins or did you just end up telling everyone right away?
