I had the same difficulties trying to decide on a resort! I chose Dreams Riviera Cancun (the brand new resort that just opened in October). I am getting married in February 2010 and our guests will be paying about $1100-1200 pp for room (all-inclusive) and flight for a 4-night stay. Although they can stay longer/shorter if they want to. I am so excited now that pictures are finally out of the resort...it looks beautiful!! And I think Dreams resorts have a good reputation. Hope that helps!
I was leaning towards the Ultimate package because of the decorations but now that the decorations can't be for the arch on the beach, I am not so sure. I wonder why that is?? Can we switch the package once we have a contract?
