I agree with jtryan. I'd also consider both resorts quite safe & family friendly.
If you are going with teens, you'd find more for them to do at the Vistana Resort, since it's much larger, with many different pools and recreation centers, more sport facilities, etc. Here, all the 1-BR's that have a full kitchen also ought to have an inroom washer/dryer. One of the pools has a short, steep, zippy slide too.
Vistana Villages has a nice looking main pool too and of course, it's newer. Here, (the web site says) units offer a washer/dryer. Have fun!
