Thanks for the info. Would you say that travelling by bus is a fairly convenient way to explore the island?

If there are 2-3 people it would be a lot easier and would save a lot of time to rent a car.

Maybe try 1-2 days moving around by bus, especially to visit easy to get places like Paleokastritsa, Dassia, Achillion etc which have very good bus connections and hard to park areas. Then, rent a car for 2-3 days, organizing day trips along the northern- southern part, going from one place to another, something you can't do by bus. You need one day for the north ( Sidari, Roda, Acharavi, Kassiopi, possibly Old Perithia for dinner) and one for the south, going from one beach to the next ( Halikounas, Issos, saint George etc)

That sounds great and thanks so much for being specific as I've never been so have no idea what to see and what to miss. I'm not sure about Corfu Twon, it's a little expensive and I'd rather be on the beach...is there a reosrt/beach area that would be central to buses and Corfu Town?

unless you stay in Corfu town, you will not be close to the bus terminal, to get buses for both north and south. If you stay in Dassia for example you'll be able to be in Corfu town in 20 min and the bus runs every 1/2 hour, but you will be able to get on buses that pass through Dassia and go north.

If you stay in Agios Gordios, where you mentioned, you'll need 30 min drive to Corfu town and not very frequent buses- -only to Corfu town.

Renting a car for the whole period, or for a couple of days can set you free to move around the island, make your own schedule, return "home" as late as you wish etc. Just organize your daily trips, not to waste time, visit places and nice beaches, so to make the most out of your stay here.
