QM2 followed in QE2's wake as she sailed across the world in 2011, she even parked the spaces specifically labelled for QE2 on the quayside.
On QE2 it was usual to guess which side first, often guessing it would be portside, as it was many times, the custom - then ask for confirmation - and then to hang out on the appropriate side on the Bit Beneath the Bridge to watch her being tied up, before legging it down aft to hang over the side to watch again...etcetera! Usually everything depended on wind direction, depths and tides, tugs on station etc - each one always a consideration given the size/acre-age of her beam, availability of turning space, other ships already in position, or waiting to be docked, and for loading / unloading, whichever side the warehouses and cranes were located. Quays in Port Everglades, Montevideo and was it Safaga(?) in Egypt, sailing in and berthing come to mind as being highly 'interesting' places to watch!

Invariably QM2 was berthed alongside with her bow pointing towards the harbour entrance - her portside gangways usually being those that were deployed.
Many older travellers still practice sitting on 'Portside out, and Starb'd back' - preferably to avoid the heat of the sun in tropical and equatorial waters on the outward bound south-easterly trade routes to India, S Africa and Australia etc.
Homeward bound would see them arranged in steamer chairs on the starb'd decks - the preferred way to keep 'sun-free' whilst sailing north.
Port-Out, and Starboard-Home. The acronym (POSH) giving meaning to the appropriately termed 'posh' as in people!
