The only caveat I would mention is that if you do book an excursion with the tour operator then you are at least guaranteed an English speaking guide, and a proper coach.
The reason I mention this is that last year we did the Albania trip, and it was only by sheer luck that our guide to the Butrint ruins was an English speaker. Some of the other coaches on the same trip had German speakers, who used English very much as a second choice.
Also, last month we booked a trip to Paleokastritsas and Bella Vista, which was advertised outside the agents (not the same agents as Albania) as "all tours in air-conditioned coaches", but what turned up was a Peugot 206, with a very pleasant young Greek man driving, who didn't speak much English. This car took the driver and FOUR adult passengers on a day when the car temperature gauge read 38 degrees! Most uncomfortable! We did enjoy the sights, though.
So, I suppose it's the chance you take.
