Pack round a US resort (5)

I believe the answer is:

tampa

'us resort' is the definition.
(resort city in Florida)

'pack round a' is the wordplay.
'pack round' becomes 'tamp' (tamp can mean to pack round or surround with).
'tamp'+'a'='TAMPA'

(Other definitions for tampa that I've seen before include "Floridian resort" , "Port of western Florida" , "US town" , "Resort in W. Florida" , "US city" .)

I've seen this clue in The Guardian.
