I already have a portable unit and a sealing kit, plus blackout curtains. The curtains can’t be deployed with the window opened enough to get the hose out. Running without any blackout curtains is an immediate non-starter since dawn is at 02:00 here, and my bedroom window is to the east.
Get one of the portable ones and get one of those kits that seal around the hose to the window and then get some curtains.
There is not a single one in stock in the entire UK, plus dual hose versions are basically non existent here too.
