If you want to see the country, and it deserves it, it is definitely no need to discount the version of the independent travel. If you go in early November and october is not bad), you can save significantly on hotels.
Ideally go by car, or take it for rent. Excursions, such as meteors, will cost at least 500 euros, and with an independent view almost nothing.
Meteora is the most unusual and interesting trip, like you will not see anywhere and never. Nature has created huge rocks where monasteries are currently hanging in the air.
You can stop in a not big village of Castra, the cost of overnight is about 33 - 35 euros per room. All hotels for a trip to Greece booked through Buking, the benefit of the GE traveler discounts there.
Interesting place Edessa. This is not a big town. But very cozy and beautiful. Right in the city is a very green and well-kept pack with waterfalls. Some large and several small waterfalls, a place to relax and walk.
The charm of such trips is also in the fact that you can inspect the sights in its pace, nothing anywhere. If something is not interested, then do not waste time, well, where, where I liked it, to enjoy the full.
Almost all hotels and guest houses offer breakfast. Greek cuisine is a separate song. I love her very much and I advise everyone to try. Better in not large taverns, where it is very tasty and not expensive.
Make a route depending on the preferences and the possible number of holidays and ... pleasant journey.
