"I don't understand what you mean when you ask for 'a nice beach." "
Well, she said she has never been there before so just looking for info about the beach. Beaches and swimming conditions can vary quite a bit depending on where you go. St. Thomas, Bermuda, Hawaii, Key West, etc. All of them have varying beaches from beautiful to stony, non-swimming, etc.
We don't plan on spending our 9 days laying on the beach. But sometimes it is nice to walk out your door and just plop down and relax for awhile on a "nice beach". Then maybe jump into the water and swim around a bit, snorkel or whatever.
