Peter,
I know nothing about the Lido's, but the original Eden has the steepest slope you can imagine fronting it between the two bunkers and it seems rather well regarded!
To be honest, the only way I'd ever consider trying to play a run up there would be if I had a really really strong wind that just made the idea of an airborne ball silly. I've had the pin cut on the precarious edge of that slope between the two bunkers both times I've played the hole, and both times managed to left a nice high shot just over the bunker on the right (Shell?) and have it stick there pin high, but I've probably just been lucky so far

The one thing I did learn was to deliberately leave that putt a couple feet above the hole, since the first time I tried to make it and had my third putt from way down below between the two bunkers...
While I think it'd be a fun challenge to try to roll the ball up that narrow opening, those playing for score would probably be better off laying up and playing it as the world's shortest par 4, to avoid the risk of playing it as the world's shortest par 6.
