We are going for a week to spain, half board, in a room that is suitable for up to 4 people. There are 3 of us going, my daughter (25) has decided to travel to stay with us for 4 of the days, she will already be in Spain and near enough to get a train to us. Who would I contact about her being in the room, the travel company (TUI) or the hotel? Will pay any extras of course.
