Groups once more seen in Ibiza and Magaluf? (7)
I believe the answer is:
resorts
I believe this is a double definition.
'groups once more' is the first definition.
(sorts or groups again)
'ibiza and magaluf?' is the second definition.
(Ibiza and Magaluf are holiday resorts)
'seen in' is the link.
(Other definitions for resorts that I've seen before include "Holiday towns" , "Brings into play: getaway spots" , "places for holidays" , "Uses" , "Haunts" .)
