Old hands on half days rebuilt Mickey Mouse town (7)

I believe the answer is:

orlando

I'm a little stuck... Click here to teach me more about this clue!

'mickey mouse town' is the definition.
I can't tell whether this defines the answer.

'old hands on half days rebuilt' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'hands' becomes 'rl' (abbreviations for left and right).
'half' indicates taking half.
'rebuilt' indicates an anagram.
'days' halved is 'da'.
'on'+'da'='onda'
'onda' with letters rearranged gives 'ando'.
'o'+'rl'+'ando'='ORLANDO'

Can you help me to learn more?

(Other definitions for orlando that I've seen before include "Shakespeare hero - book by Virginia Woolf" , "place in Florida" , "US city" , "The city in America" , "2016 Invictus Games city - Virginia Woolf novel" .)
