For a few weeks we have had plans with a couple to come over for NYE tonight (they are boyfriend, girlfriend, together about 2 years). The guy is my husband's best friend. A few days ago, another couple decided to join us (they are husband and wife) and the girl is my best friend. Nothing has been mentioned of where everyone is sleeping yet, but we only have one guest bedroom. The other couple will have to blow up an air mattress and sleep in our den.
Who gets the guest bedroom? The married couple? Or the couple that we had plans with longer?
