10 Lounges in ONE DAY - Heathrow Terminal 3 lounge hopping (Cathay, Qantas, BA and more!)

Heathrow (LHR) Terminal 3 (T3) is known for having a huge number of premium lounges in a single terminal building. Out of the 12 lounges inside, I have access to 10 of them, so I ventured to visit each of them in a single day.
I checked out the British Airways Galleries Club lounge, British Airways Galleries First lounge, No1 lounge, American Airlines Admirals Club lounge, American Airlines International First Class lounge, Qantas International lounge, American Express Centurion lounge, Club Aspire lounge, Cathay Pacific Business Class lounge and Cathay Pacific First Class lounge.
I show what each lounge has to offer, how to get there, my thoughts and what the access requirements are.
Let me know if you've been to any of them or which one was your favourite in the comments!
