I posted this before but I'll be happy to share the information again. I just did something similar to this a couple of weeks ago. I went to the Radisson instead because the beach is nicer. The water was blue blue and crystal clear and there were lifeguards. It's right next door, but I walked over to use the Wyndham pool and the Wyndham has a nice grill for lunch. There are 2 ways to get there. One is to take cab, they charge you per person $5-$8 each, but what my DD and I did was to take the #10 bus. for $1 each pp payable at the end of the trip. I'm not a bus person, but this was very easy and the cheapest excursion I did. LOL
Then I walked through the lobby and out to the beach, there were tons of beach chairs. I later walked next door to the wyndham to grab lunch and swam in their pool. A local on another board posted that providing you bring your own towels and don't make a nuisance of yourself the hotels are ok with you using their facility.
On the way back, I walked out to the street and flagged the #10 bus down. We got in and for $2 more they took us back to Nassau. We had time to do some shopping before it was time to get on this ship.
We had a great day.
