Valentine`s Day Party

Hi there. My husband and I are planning a Valentine`s Day party for couples. We need some help on how to make this a great hit we`ll all remember. We were thinking of playing truth or dare Jenga, having a scavenger hunt and then everyone wins a prize, but you get a big prize if you`re the first one back. What other things can we do liven it up? Any games that would work well with couples, or anything other suggestions? Thanks...
