I have a cousin who moved from the Dearborn, Michigan area to Tampa Florida and bought a nice inland condo there. I have a nephew who moved from Idaho Falls, ID to Orlando after being in the Disney College program, decided he didn't want to move back, found full time employment in Orlando, and bought a cute small home in an ethnic neighborhood there (at age 21 after renting for about three years). Both are totally sold on Florida.
My cousin is really into church, bible studies, and things like that and that was a great route for him for making friendships. He has some great friends in Tampa now and doesn't miss cold Michigan winters at all. The heat and humidity, though, have been an adjustment in his schedule for getting exercise, etc. It's just so hot for so much of the year. He for example walks 5 miles with a buddy every Monday, Wednesday, and Friday all year round, but gets up really early and does that walk at 5 a.m.
My nephew is gregarious and a bit of an organizer. He makes friends easily, has his neighbors over a lot, and has so embraced the outdoor lifestyle of Florida. He is quite handy and built an amazing deck and gazebo for outdoor entertaining, picked up a great used hot tub for his back yard too. He loves all kinds of food and is really enjoying making new things and shopping at the nearest grocery store that has lots of ethnic offerings. He's gay and very much enjoys it that Orlando is more liberal socially than conservative Idaho Falls. ID where he grew up. He loves being in a larger city too with all the great cultural amenities Orlando has to offer - concerts and theatre in particular. He has really gotten into all of the outdoor nature opportunities nearby too (previous to moving out really just knew more about theme parks, etc.) and does quite a bit of kayaking (invested in a Kayak). For theme parks he gets a season pass at SeaWorld annually. Has sometimes has gotten a season pass at Universal -- I don't think he got that this year though. Disney passes are just way too expensive, but he has friends who work for Disney and if he goes there he usually goes with them.
I am actually surprised my nephew hasn't really missed mountain outdoor activities -- He used to work at outdoor camps in the summers outside of Jackson, WY -- They liked him so much there and he's such an organizer that they would tell him -- We want you back -- tell us what you want to do (cook, outdoor adventure outings, photography, lead theatre activities - he did all that stuff). His family did a lot of camping, boating, skiing (family season pass at the fabulous Grand Targhee ski resort) / so close to Grand Teton and Yellowstone and so many other lessor known outdoor areas, and he used to say when he grew up he'd like to move to Alaska. But then there was the Disney College program and he absolutely fell in love with Orlando and all it has to offer. He like my brother would be who I'd like to have around if I'm on an outdoor wilderness adventure -- my own mountain man who knows what to do it seems in every situation while we (although we have camped a few times) are more city slickers.
I think the hardest thing for my Nephew in Orlando is being farther away from family. But if you live in Orlando, everyone does come down and visit you a lot.
I don't stay with either my cousin or nephew when I come down (would work if I traveled solo, but for me I always come down with family), but they are two of my favorite relatives for sure, and since they have been in Florida, I've doing a mini budget trip annually -- combo of visiting them and doing a few theme parks (just a really fun get-a-way)
Please note that neither has children at this time.
