Can we have snacks and drinks on the coach?

Yes, but please no glass containers.  Drinks with lids are advisable, so no cans.  If you plan on bringing a cooler for drinks, it may need to be kept in the luggage bay.  Please do not obstruct the aisle.  Be considerate of others with snacks and trash.  Your driver has to keep the coach clean and will be as ready as you are to get off the coach and get some rest!
