Have you been there previously, or just read the reviews and done your research? I won't have time, and don't want to spend the extra money, to do a site visit first. I have been researching the Iberostar chain. Did you look into them at all? You are DEF saving TONS of money! That is GREAT! Your prices are very good for your guests too! How many people do you have booked to go down for the wedding?
i went to all 3 iberostar locations and secrets this year (on my hunt for a wedding location). iberostar grand was beautiful, adults only! they have a gorgeous entry and staircase. iberostar suites is nice as well, and beach was the one i liked the least in decor and overall look compared to the other two (iberostar beach the cheapest also). they are all located next to eachother in that order. im pretty sure i still have pricing for both iberostar and secrets if you need it.
secrets is beautiful and much smaller than iberostar, it's secluded on its own peninsula. i'm going again this weekend to finalize some stuff. there are a few girls who created planning threads that show pictures of secrets.
