Me and my newlywed wife are heading to Greece for 14 nights. We're gonna spend a 3 nights on Crete, 4 on Santorini, 2/3 on Naxos, and have 2/3 more for either Ios or Mykonos. Budget is important and I've heard Mykonos is a bit over-priced. I've also heard that Ios has a fun nightlife and would be a good choice. Any recommendations?
