What about a nice weekend (or just a night) at a couple's getaway??
There is a place not far from us and we have gone a few times. The cabins all have fireplaces and hot tubs, and NO kids are allowed. Sometimes it really is nice to get away from the phone, door bell, etc.
Several years ago, we sent the kids to the in-laws and went to dinner in a nearby resort type town (in the mountains). Over dinner, my husband asked me if I packed my toothbrush. For dinner???
He had made reservations at a hotel, with a hot tub in the room, while I had taken the kids to the in-laws. It was really nice, even for an evening, to get away from the house and be somewhere different! I like surprises like that.
