Team touring Portugal heads to resort spa and rests (7)
I believe the answer is:
spiders
'rests' is the definition.
(I've seen this before)
'team touring portugal heads to resort spa' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'touring' means one lot of letters goes inside another (touring can mean going round).
'portugal' becomes 'p' (common abbreviation eg on car number plates).
'heads to' suggests taking the first letters (I've seen 'heading to' mean this (the head of the word)).
The initial letters of 'resort spa' is 'rs'.
'side' placed around 'p' is 'spide'.
'spide'+'rs'='SPIDERS'
'and' is the link.
(Other definitions for spiders that I've seen before include "14 [BOWIE] 's band from 26 [MARS]" , "Predators on the web" , "Arachnids" , "Insects; rests" , "Web weavers" .)
