while i don't know much about any of the mayo programs (other than i was rejected from the Rochester one today), all i can say is don't underestimate the location of where you do your training when deciding where you want to be. unless you have family nearby, i would imagine rochester is a very cold and lonely place to be, and it's not the most easily accessible place to be. there's an airport, but only 2 airlines fly there and i'm sure it ain't cheap, and the closest "big" airport is Minneapolis/St. Paul which is 80 miles away. This isn't so much a concern for you cause as a resident you won't be traveling that much, but i can't imagine my friends and family being eager to visit when it's a hassle or expensive.
i did apply to the scottsdale program, which if invited i'd be more willing to consider because it's easy to get to, the weather is great most of the time, and the quality of life is probably better. i imagine the same goes for the FL program as well. you won't care about how much better the rochester campus is if you're unhappy and lonely being there.
congrats on the invites though!
