Hey, We decided on the Iberostar Punta Cana for Oct 2013. It's not adults only, but there is an adults only resort part of the Iberostar chain if that helps. We went online and did a lot of research on what the reviews were like based on selloffvacations.com and tripadvisor.com. We also found a great travel agent who had been to the Iberostar chain and also found lots of advice on this forum as well. Hope that helps a lil,
