We have been to Mykonos and loved it. However, we plan to return to Greece in October and want to visit the Islands. We heard Naxos was beautiful but we have to make a choice between the two islands. Naxos or Mykonos. Help!!

How about Santorini?

We plan to spend two nights in Santorini but want to select and additional night in either Mykonos or Naxos.

Naxos or Crete

I'd say Crete or Cyprus instead.

Cyprus?

YOu say you have 2 nights Santorini and ONE night more for another island? That is not worth doing ... half a day minimum for the following: pack, check out of Santorini hotel, get to dock, wait for ferry, 2-4 hours on ferry, disembark, get to hotel and check in. I estimate 8:30 - 3 pm. Then next AM, do the same. If ONE day is all you want to allocate, stay in Santorini.

That would not be an island experience, just a transport experience.

I agree with Janet. Naxos is great but for one day/night you would be better to rent a car and explore Santorini.
