I'm looking to book a late deal (2nd/3rd week in May) to a Greek island and I just can't decide between these 2 islands - and which resorts on them to look at. I'm 3 months pregnant so my husband and I have decided to have a holiday while we can! We are mid-30s and want somewhere authentically Greek with a good selection of places to eat but want to stay away from big nightlife areas. We are looking for somewhere that has some pretty easy-going walks, ancient sites, picturesque areas and boat trips. I was thinking either of these islands because then we could do a day trip to Olympia. I've been to Kos (a bit dull IMO), Crete (great history) and Santorini (gorgeous!) so far and love Greece so really looking forward to going back. Any advice would be much appreciated!
