We booked a Sun holiday for the first Friday to Monday of the school holidays. MIL & FIL haven't had a holiday this year and do lots for us and SIL so offered to upgrade for them to come. Ive just called the Park Resorts site and they are fully booked so we cant change the booking.
Would it be unreasonable to let DC (7&4) sleep in the living room, with make shift beds as no pull out beds apparently, so they can come with us?
