We are going to be traveling from Gatwick airport early morning and will be staying overnight at a hotel the night before. Planning to travel at lunch time when our youngest has his nap. Where would you recommend to go to pass a couple of hours with a 5 and 2 yo? A playground or nice village or something nice to do, then ideally somewhere to have dinner? Ideally within 20mins of the airport (we will be travelling via the m1 and then m25).
