Disembark in Gold Coast’s second city (7)
I believe the answer is:
orlando
'city' is the definition.
(I've seen this before)
'disembark in gold coast's second' is the wordplay.
'disembark' becomes 'land' (I've seen this before).
'in' is an insertion indicator.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'coast's second' becomes 'o' (I can't justify this - if you can you should give a lot more credence to this answer).
'or'+'o'='oro'
'land' inserted inside 'oro' is 'ORLANDO'.
Can you help me to learn more?
(Other definitions for orlando that I've seen before include "Bloom for one" , "City in Florida - site of Disney World" , "place in Florida" , "The city in America" , "somewhere in Florida" .)
