I will be flying with XiamenAir (MF) business class in the springtime and I will have a 10hr 30min connection in Xiaman airport (XMN). Arrive in XMN at 1:40pm and depart at 12:10am.

MF seem to offer 3 choices for transfer passengers (https://www.xiamenair.com/en-eu/PassengerService/Ground%20Service/Xiamen%20Hub%20Transfer%20Service.html):

1) transfer lounge
2) transfer sightseeing
3) transfer accomodation

It seems passengers can only choose one of the three. I think the sightseeing is the best option because in the hyperlink it says 'The transfer lounge does not provide meals and hot food.' so I don't know what the lounge offers other than a chair and WiFI perhaps. But as a business class passeger I assume I will have access the the lounge after the sightseeing. Also, I wont be tired to sleep at the hotel as I'll sleep on the flight and the hotel option also requires paying for the transport to/from the hotel using Renminbi only. However, the sightseeing bus operation time is 08:30am - 4:30pm so I will be in time for it. But how frequent is the bus(es), how long is the sightseeing tour and what would I need to do with reagrds to embarkation/landing card? I already have an in date 2 year UK citizen tourist visa for China.

What are the recommendations and feedback from others who have transitted in XMN on MF flights? Thanks.
