We have also had that problem. This time it was opening the door to the balcony. I bought a nightlight from Wilco but it proved to be too bright. Hope you have a lovely holiday.Very interested in all your comments re holidays. One problem I have learnt to deal with when we are in a new and different environment is OH trying the wrong door when looking for the loo at night. When it happened at a large coastal complex he was found downstairs beside the pool - understandably very upset as was I. Now I know to barricade the outside door and leave night lights on. I know it sounds like a fire risk and I suppose it is but the getting lost risk is much more likely. Looking forward to a cruise next week...fingers crossed!
