My only real suggestion is that we loved Waterbrook winery near Walla Walla when we were there a couple of years ago. I wanted to spend the whole day on their patio. It was just so, so lovely. Lots of wineries in that area to visit, but that one stood out to me.

If you head closer to Yakima, I've always wanted to stay at the Cave B Inn. It looks beautiful and they have a bunch of luxury yurts to stay in.
