This! We have done Alaska several times and in several different months. August will be fine for an Alaska cruise. We've cruised the Italy, Turkey and the Greek Isles itinerary in May, August, and October. I would never have chosen August, but it was the only time my son and DIL could take vacation. Never again, though. It was SO hot, and the crowds were awful. October is by far my favorit time of year for this itinerary.
