Either in your apartment or in a hotel? Or maybe in a separate house? How do you feel about it? Do you let them know you can hear them? We just moved to a new apartment and can really hear the couple downstairs really clearly. I'm surprised they can be so loud with kids. It doesn't necessarily bother me, but I kind of want to leave a note on their door that says "Glad to hear you had fun last night!!" just for giggles. Thoughts?
