thank you for all your replies i think you right i will book this before we cruise and use the OBC elsewhere hopefully. was not aware i could cash out at the casino hopefully i can?
this is our 1st cruise i've heard the le petit chef is ok worth doing only once, however looked at the menu does not really appeal tbh.
might look at the gift shop.
i have booked concierge class not really sure what extras this offers beside welcome lunch. the price was comparable with the standard cabin with sea view.
