If you ask your room steward they will certainly arrange this for you and if there is a problem just go higher, Head Steward then Hotel Manager, but there should be no problem apart from Artemis having these damn stupid beds.....Nei.
All you have to do is ask your cabin steward.
We have our beds made up into a large double and keep it that way as we too like a nap before dinner.
We book the restricted view cabins and find them very comfortable with a view,bath and larger than Oceana,Oriana or Auror.
Thank you to both respondees. Has definitely reassured me and my mother.
