I booked a room for my mum and dad and me at a Travelodge...a family room, and now DP wants to come, so i've booked a double. Its a saver room, so can't be amended, but i'm afraid that when the four of us check in, they won't let us stay because we booked a family room for 3 adults, and a double for 2 and there will only be 4 of us...help!
