We will be flying from Gatwick north in June with a 16 month old and 3 year old. Flight is at 11am so travelling down from midlands through rush hour if we were to travel on the day. However, neither children are great at sleeping in unfamiliar places and I think we'd end up getting less sleep and having two very tired grumpy children on the plane if we booked a hotel near to the airport the night before. Pre kids me and DH would have just booked a room. What have others done and how much extra time should I factor in for rush hour? TIA.
