We currently have a kind of au-pair but she's the niece of a good friend so we treat her very much as part of the family. This includes her (very occasionally) giving up her room to an older relative coming to stay for a night - when she would sleep on a sofa-bed instead, and (slightly more often) allowing us to use 'her' room for guests when she is away anyway (e.g. for a weekend visiting friends). She has no problem with either of these arrangements.
She is leaving in May and we are planning on getting someone new. But it is unlikely to be a family friend, so we are worried about what to do in these situations. The bed in the au pairs room is the only one suitable for a couple, or for older visitors, so though we are happy to put visiting young adults on the sofa bed there will be some who can't do that.
My worry is that the room an au pair gets is their only private space and should not be used by others at all; my DP says they are young, flexible and won't mind, and where she's from (New Zealand) it's quite normal for kids / teenagers / young adults to be moved around for guests and no-one thinks anything of it. She thinks I'm quite barmy even for worrying about it.
The other option I suppose would be to give up our own room instead (and sleep on the floor somewhere).
If we make it clear when we recruit that they may (rarely, e.g 3 times a year) be asked to give up their bed for a night or two, would that be acceptable do you think? and is it normal to use their room for guests when they are away for a weekend?
Do you agree with me or DP?
