Congratulations Catwilliams! I almost booked my wedding at the same time!!
It was a REALLY tough decision but I ultimately chose Hilton Papagayo over the RIU Palace. FI and I went to visit in July because I was so torn between the two, seeing the places made us lean towards Hilton. It's a little more intimate, even though we're having a rather large wedding, about 80 guests. I think our guests would have had a great time at the Palace also.
