I want to take my son who is a major train enthusiast on the Night Riviera train from London to Penzance in late August. He knows about the gradual refurbishment of the carriages and that coach D in one of the train has been done up. So far, no matter what way we try to book we cannot find out if the cabins we plan to book are refurbished or not. Do you know if there is any way to predict if the cabin you book will be refurbished or not?
