We have a family holiday coming up, the first one we've done with extended family. The villa we've booked has two floors, with a double bedroom and a twin bedroom on each floor. There are 3 couples (DPs, DB and SIL, me and DP) and two children (mine) coming. The children will obviously take one twin bedroom. I'd happily take the other twin room but then that leaves the DC on a different floor and they do get up in the night (they're 5 and 8). Me and DP are arriving first. I don't want DB and SIL to be narked with us for nicking the double bedroom up for grabs. I think I might be over-thinking this but have got my head in a tangle. WWYD?
