Tom the actor has holiday afloat (6)
I believe the answer is:
cruise
This could be a double definition.
'tom' is the first definition.
(Tom Cruise)
'holiday afloat' is the second definition.
(I've seen this before)
'the actor has' is the link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for cruise that I've seen before include "Pleasure ocean voyage" , "Coast" , "Ocean trip taken for pleasure" , "Voyage for holiday makers" , "Sail to and fro" .)
