Ok, people... i need votes... i'm planning a May vacation and I really wanna go to New York City, mainly so I can shop at H&M, but I'm not too sure how much I'm gonna like the city, cuz I've never been. I also really wanna visit all of my friends in San Francisco, a city that I know I love...

so...

am I crazy to think that I can fit both of them into a vacation?? Say, a day flying... three days in NYC... another day for flying... and four or so days in SF, before flying home?

Input please...
