Alternative to Craigslist personals

I'm just wondering what people use in place of Craigslist personals now? Maybe this is an old subject but my husband and I haven't had many chances to play in quite a while. We used enjoy Craigslist to find others (man/woman) to join us whether that be in our town or places we visit. We've been given the opportunity to get away child free this weekend and we're wondering what other options we have? We're in Wisconsin if that makes any difference.

Edit: I should add we're maybe too old for the Tinder game. Mid to late 30s
