We have now been to all 4 Couples resorts. Our plan was always to try them all but to be honest, CTI appealed to us the least when we first started investigating the various choices in 2006. So, it was with a little apprehension that we traveled there last week.
We knew not to try to compare them as they are all so different but what we were not prepared for was how much we liked CTI! Was it perfect? No. Would the imperfections keep us from returning? Definitely not.
Report:
After a long day we arrived at the resort at a little after 5PM. (We just missed orientation). The time from getting off the plane to leaving from the Couples lounge was only about 45 minutes.
Check in took a little while as there were two buses that arrived at almost the same time but we were greeted with cold towels and a rum punch that had quite a punch! There was a plumbing problem with the room we booked (Ocean Jr. Suite) and they offered us the choice of a Premier Ocean room or to wait a half hour so that they could turn the water back on. We chose to wait and we were glad we did. The room (3404 - top floor in main bldg.) was lovely; spacious and comfortable with a gorgeous view! The bathroom was also large with separate jacuzzi tub and shower. The shower had a large enough lip that no water ever got on the floor. Each room had it's own balcony as well. We loved our room!!
We took advantage of many of the offered activities and water sports as we are not a "lie on the beach" couple. The beach however was nice and the water perfect. We never got into the pools but they looked fine as well.
Food was good overall and service excellent for the most part.
We did not enjoy the food at Bayside and the service was very rushed. Others liked it but it was not for us. The Verhanda and 8 Rivers were great; we had dinner at each twice. The Patio tended to be a little repetitive at breakfast in our opinion but at lunch time you had a choice of the Pool Grill and the Veggie Bar as well as the Patio. We are not big "foodies" but this is the one area we were slightly disappointed with.
The staff from the groundskeepers on up were friendly and helpful. You certainly get the feeling that you are a valued guest! I must attribute this to management as they set the tone for the entire resort. The GM, Mr. Leonard Henry, was almost always present. We had two minor problems (that I won't go into here)which were addressed and resolved within 10 minutes.

One suggestion that I might offer is that upon check-in guests that are pre-registered receive a packet containing their return perks; that is, massage vouchers, gift shop voucher, invite to Repeater's Dinner, Couples shirts, etc. We received nothing without asking. We also never received any departure info at all.
In spite of these minor flaws we thoroughly enjoyed our stay and in fact rank it as one of our top two Couples resorts.
Would be happy to answer any questions.
