Hi Denie,
I have done this just last year.
I used "Resort For A Day" (not sure if same company as yours)
We did go to Sunscape.
We were 3 married couples age 35 - 70.
The Good: very nice property, very friendly staff, no issues getting chairs or umbrellas on the beach or around the pool, no issues getting drinks at the swim up bar (best part of the day), check-in at front desk was fast and easy and they gave us a welcome drink (and maybe a cookie), no issues getting lunch at the buffet (more on this later), beach was clean and huge with soft but VERY HOT sand.
The (semi-) bad: The food at the buffet was mediocre at best (no one got sick though), somewhat limited food choices, beautiful setting though for the buffet (outdoors overlooking pool, but covered), good drink service at buffet, it was a bit crowded when we went (May 2022), resort is pretty big and a nice (long) walk from lobby to the beach.
The biggest issue was the beach vendors. They hound you all the time to the point we had to leave the beach and go to the pool. My wife actually bought 2 beach towels from them thinking they would leave us alone, but it just made it worse with many more approaching us. They were in the shaded spot on the beach, but if you stay in the full sun it probably would not be too bad - I like/need shade.
At the end of the day, for the $59pp we paid, I would probably go back in the future, just avoid staying on the beach - again no issues around the pool. I drank more than the $59 fee we paid to get in.
Don't remember how far from the port (but it was fairly close) since we took a private city tour first, then the driver took us to Sunscape and came back later to pick us up. I would have probably cut down the tour by about an hour and spend the extra hour at the resort (but that was a little poor planning on my part).
Any questions just let me know.
