Dominican Republic (Punta Cana) All-Inclusive Resort Recommendations?

I am planning a trip to the Dominican Republic this August or September for 8 days, 7 nights. I have done my fair share of researching the resorts and am torn between RIU Palace Macao and Dreams Resort, both in Punta Cana. Does anyone have experience with these, preferably both, and can offer advice? I like Dreams a little more, but I know if we go to RIU then we can visit any of the other RIU Resorts as well. It is a vacation for my boyfriend and I, if that helps. Any other advice would be great as well. Thanks so much.
