This question already has an answer here:
A friend and I have booked a package holiday in Spain later this year. I have one more friend that wants to join us as he can get booked on the same flight. But the reservation is for only two adults, not three. On the booking it says the room sleeps 3 and has a pull out sofa bed. Do you think he will be alright (6 nights) if we take his bag upstairs for him on the first day and he comes up to the room 3 minutes after or before we do throughout our stay or will he get caught and if we do get caught what will happen?
