FOR THE LOVE OF GOD, PICK HAWAII. Seriously. The weather in NYC during July is possibly the most disgusting thing ever. There's nothing but relentless heat and humidity, lasting well after sunset. And woe betide the unwary tourist who takes the subway at high noon, when the platforms heat up to about 110 degrees. Plus, everything smells.

In conclusion, HAWAII HAWAII HAWAII. There are beaches. Gorgeous beaches free of medical waste! Beautiful clear water that is actually capable of sustaining sea life!
