First, I have learned so much through combing through the archives -- thank you all for the advice you've provided, it's been very helpful as I've planned my trip! My husband and I will be arriving in Greece on May 31st and will stay through June 15th. We will be staying 5 nights in Santorini (this part of our trip is fixed), and are planning 4 nights in Sifnos, 4 nights in Naxos, and our final 2 nights in Athens. Sifnos is something I decided upon only after reading all the threads on this forum that mention how beautiful the island is! We had also considered Mykonos but decided against it after reading more about it through this forum and guidebooks (we're not the party type and don't want something too crazy).
I was wondering if 4 nights on Sifnos is considered too much and if 3 would be better? If we shifted it to 3 nights instead, we would add one night in Athens, making it 3 nights in Athens instead of 2. For context, this will be our first trip to Greece. My husband and I are in our early 30s, and are looking to have a relaxed vacation exploring the islands. On vacation, we enjoy a relaxed pace of life, good food, sightseeing, beaches, some shopping, and also visiting historical sites. For context in case it's helpful, our favorite vacations in Europe have been to Italy, Spain, and Croatia -- we love the mediterranean lifestyle!
Thanks very much!
