Dominican with teens
 

Any suggestions on where(geographic location) to stay in the Dominican Republic with teenagers? I just don't want to be too secluded, because I think they will get bored. Looking at different options: hotel, all inclusive, home rental?

Are you set on going to the DR? There is really not a lot to do if you want to go off on your own there.
An all inclusive resort would offer activities for them.
If you are not set on the DR, I would recommend the Playa del Carmen area of Mexico. Lots to do on and off resorts.
