My whole family is very conservative, and my boyfriend and I are not allowed to sleep in the same room.
There are four bedrooms: One for parents, one for brother and his wife, one for my boyfriend, one for me.
Now. My aunt and uncle are PROBABLY going to hear about my whole family giong to my grandparents place, and are PROBABLY going to decide to come as well. Which leaves one person or couple without a room.
How should the room situation be handled if my aunt and uncle decide to come?
Aunt and uncle sleep on a cot/bed somewhere in the house or get a hotel room - they were the last to decide to come and therefore get last dibs.
Boyfriend sleeps on a cot/bed somewhere in the house or gets a hotel room - he's only one person and he should give his bed up for a couple
OP sleeps on a cot/bed somewhere - her boyfriend is a guest because he isn't family and should allow everyone else to have a room
