3Mickeys,
Yes, it is a superb arrangement. We learned about it from others on cruisecritic.com. We just walked through the lobby and out to the pool. We even had our towels from the ship. We were cautious at first, but no one cared. The wait staff were all very nice.
We had debated renting a "day room," but did not because we could not be guaranted early check-in. We were very happy we did not. We also had considered taking an excursion to a beach, but did not.
In the end, we only paid $26 ($1 bus fare each way times 13 people), plus a modest amount for drinks and food (probably $200 total) instead of the $780 we would have spent on the excursion. And, as you know, Cable Beach is beautiful.
