We have an exchange student (15yr old) staying with us for a month in January and DH has also invited his parents to stay for a weekend. We only have one spare room so this already means our 2 kids bunking in together and no extra beds. Now DBIL has asked us to have his 2 kids for the weekend as DSIL is away and he wants to go to a party and then a day out with friends on the Sunday.
I feel inclined to say sorry, no, already got a houseful including a teenager we've never met and are expected to entertain and "show London" plus juggling kids sporting commitments and entertaining the grandparents.
But should I just relax and go with the flow, another couple of kids won't make a difference?
