Indeed, I think it is quite dull. Five movements a day means a 2 hour wait between them
I was there when the Turks, Emirati, Swedes and Danish were there in 2011. Very easy base to spot. Photography at finals and you can look from the opposite side along most the base perimeter from the river embankment and see everything that is there, albeit from a distance. You will surely need a big pole and not sleep in until 0830, but just after dawn and before dusk it is quite do-able.
Besides, you can fly for two hand fulls of euros to Trapani with Ryanair and make a combination (Trapani also nice in approach and open on many sides for looking).
