     Luggage

     We ask you to keep what you bring with you down to one mediumsized suitcase per person on board

the bus.

     Seat Arrangements (安排)

     Special needs for particular seats can be made on most bus breaks when booking, but since

arrangements are made on a firstcomefirstserved basis, early booking is advisable. When bookings are

made with us, you will be offered the best seats we have on the bus at that time.

     Travel Documents

     When you have paid your deposit (订金), we will send you all the necessary documents, so that you

receive them in good time before the bus break departure (出发) date. Certain documents, for example,

air or boat tickets, may have to be kept and your driver or guide will then give them to you at the proper 

time.

     Special Diets

     If you need a special diet, you must tell us at the time of booking and provide us with a copy of the diet. This will be passed on to the hotel or hotels on your bus break. However, on certain bus breaks, the hotels used are tourist class and they may not be able to prepare special diets. Any extra costs must be paid to

the hotel yourself before leaving the hotel.
