I am getting married at Dreams Los Cabos and am also using Teresa. I kept adding resort choices, taking them away, bringing them, but something kept bringing me back to Dreams. Ultimately it's going to have to be about what you like. I ended up going with Dreams based on the reviews on here, the all inclusive aspect, the reviews I got about how the resort photographed from different photographers and the reviews on Trip Advisor. As soon as reserved my date, I started having buyer's remorse and started looking at other places just because I felt like I had made a haste decision. I am however, still with Dreams! LOL. I say make a pros and cons list of each resort, that's what I did. As far as four months, I have seen many people on here do it I just know I couldn't! I can't make decisions easily (obviously) and my guests would need more time since I have about 45. Congrats and good luck!
