Sounds like us. We went to CTI for our honeymoon in 2009, then tried CN in 2010 ... and 2011 ... and 2012 ... and 2013. Hmm, there seems to be a pattern here. That said, we are already booked for CSS in 2014, mostly to check out SSB.
My wife and I got married at CSS this past March. We LOVED it!! But we want to explore the other resorts, so we are doing a split stay. CN April 19-26, CSS April 26-May 3. We are trying to find some people to do a flight transfer from CN to CSS with, to split the cost, but if we can't do that, we might fly from Montego Bay to Negril. I have heard it is an amazing experience.
