We are 2 American women, who are planning on celebrating our 60th birthdays & friendship of 46 years, by spending 2 weeks in Greece & the islands, this September. We really don't have any certain destination in mind, other than spending a few days in Oia. We enjoy smaller villages, rather than big cities & enjoy day trips, to the areas around the place where we are staying. We would like to visit 1 or 2 other islands but have no concept of what any of them are like or the transportation available to get us from 1 island to the other. A big consideration is that we wish to spend no more than 120 USD/night. Any suggestions would be appreciated.
