Hello Md_ocr!
Both COR & CSS are fairly quiet & laid back. CSS being the quieter of the two!The Riu Ocho Rios is a fairly high energy experience- there is always something going on at the activity pool and with the nightly entertainment, so it will be quite a change going to the smaller, intimate, laid back Couples resorts. After the wedding and visiting with family it may be just what you need!
As much as I enjoy the Couples products -in my humble opinion- the age and needed rennovations at COR will be glaring when you are just coming from RIU. When I was there in May the RIU was still "sparkly", the rooms updated and facilities were all very modern (as they should be with a newer resort !)
COR is an older facility that has quite a bit of charm of it's own but it is due for renovations in the rooms and some public areas.
CSS would be my personal choice for the Ocho area, it's a bit classier on the whole, many of the rooms have already been renovated (keep in mind that it was soft renovations - and that Couples philosophy is simple and comfortable) but it is also quieter. The free tours that COR offers that CSS doesn't are the catamaran cruise & horseback riding. I believe that COR has a few more water activities also.
I know it's a heck of a ride to Negril from Ocho but I would endure it and stay in Negril at either Couples Swept Away or Couples Negril.The Couples resorts in Negril are fab! Maybe take in a visit to Rose Hall-if you like ghost stories, do some shopping in MOBay to break up the trip. Staying inNegril would provide a whole other dimension to your visit to Jamaica. Ocho has that rugged, lush beauty with the mountains rising up from the sea and all of the small beaches. Negril has that fantastic 7 mile beach where you could walk forever. Plus the sunsets there are breathtaking!
My husband and I are taking our first real vacation (without the kids-woohoo!) this December and we are staying at Couples Swept Away. I can not wait to lay on the beach and just stick my flag in the sand when I need a drink!
Another option ( if you want to stay in Ocho Rios and at a more modern facility) may be to stay at Sandals Grand Ocho Rios,(large resort) or Sandals Dunnes River Falls Villagio ( midsize resort with a very Italien flair!). Of course these don't include any of the free tours that Couples does - like to Dunnes River Falls or the horseback riding but they do offer the kyaking, golf, diving, sailing, ect. Sandals is offering an up to 55% off sale at the moment.
Feel free to drop me a PM if you have additional questions!
