I needs a mans advice on how to spice it up tonight.?

My husband and I have not had time away from our 2 children in a quiet some time. We want to go to a fun park to play putt putt and out for dinner. I want to add a little spice to tonight and maybe he will want us to spend more time (just the 2 of us)....and just because I think it will be fun. I thought about wearing sexy panties, then slipping them off under the table and putting them in his pocket/hand to give him something to think about. Or not wearing any at all and wear a dress. But I would love to hear some other ideas too. Can someone please offer me theirs. Thanks! : )
