Yes, but not on Valentine's Day itself. My parents were able to watch our kids for a few hours the Saturday after Valentine's Day. Our dates are far & few between so we are really thankful to have some kid-free time together!
We took a family trip to Magic Kingdom! We got to go on one roller coaster ride kid-free, so it was like a 15 minute date :) The trip just happened to line up with Valentine's Day. We don't usually do anything.
