We had a 7am reservation for Chef Mickey's and while one member or our party went to reception at OKW to order a taxi,two of us stood outside and what arrived? A bus to MK at 6.30am! And it wasn't opening until 9am that day. Not only were we the only ones on it but he dropped us at the Contemporary entrance instead of the bus stop. We tried to tip him but he said he wasn't allowed to take it. I have read that early buses are put on for breakfast guests but we would always be ready to get a cab if a bus didn't arrive.
