"Booking required by phone". This was specified on the holiday deal. We soon discovered why - their policy with us was "if we haven't written it into your travel documents, then we don't have to provide it". Over and over we requested they correct the document they sent us so that we could get what we had paid for - they kept sending it back without lots of the features that were supposed to be included. When we complained, they treated us like dirt.
Don't use them - you've been warned!
