Airport departure lounges, worth it?

Have a 6am flight from Stansted in the summer, and am torn between:

1. Driving after work, staying in a hotel, heading to the terminal an appropriate time before the flight (no lounge)
   
2. leaving in the early hours of the morning, getting there early, hitting the lounge at 4am (opening time) and rinsing it for 90minutes before boarding
   
3. as 2 but just going to Pret for breakfast (no lounge)
   
   

Only had lounge access once due to BA bollocking up seats and it was part of the compo, but it was later in the day and I caned the free London Pride.
No idea what the Stansted lounge is like or even if they have much on at 4am.
