I am researching our first trip to Greece very excited! was wondering what ppl felt about the first week of june compared to mid-september? which is better over all? pros and cons? would like it to be warm enough to swim and sunbathe. the tickets are cheaper for september by $200. are things still going to be open in sept? how is the cosmopolitan suites? i'll probably be booking thru costco travel and that was one of the hotels listed. how does it compare to say ikies or katikies?
