What do you do about excessive barking?

I am hosting two dogs for a few days who are very sweet and friendly. However, I have come to find that they are excessive barkers in my home. I am not sure if they are normally this way or just adapting to the new environment. I have not contacted the owners yet since it is almost 1 am and tonight is night one of their stay. The owners stated they were dog friendly which they are for the most part but they bark at my dogs (I am now keeping my dogs separated), bark at any noise they hear inside or outside of the house and bark at dogs or people they may see through the window walking outside. They do not listen very well when telling them "no" or "quiet". I tried crating the one who barks more and she continues to bark in her crate. I have neighbors on all sides of my house and can't have dogs barking at 12 am, let alone after 10 pm. The dogs did not nap all day since 11 am since they were playing most of the day/running in the backyard, somehow they are still not too tired. Tomorrow I will start taking them for long walks but wondering if anyone else has suggestions to get through this weekend stress free, for both my household and these pups. I was considering taking them to the dog park to burn off some energy in addition to their walks since the owners stated they normally go to dog parks but I do not feel comfortable doing this after seeing how they react to dogs. Also wondering what others have done when they've had any issues with their clients. Thanks!
