Any beaches to recommend?

Hi, we're a group of 10ppl. mostly senior from 60-70. We will be there in january 2019 with NCL Bliss. We just want to go on a nice clear water beach and maybe some snorkeling where it's easily accessible by taxis. Any one has recommendation? any entrance fees? chair and lounges?

Also, how do taxi work? how much ? we don't want to miss the ship on the way back home.

Thanks

Cable Beach is a good beach with lots of choices.

We took a van cab taxi for $5 pp.

on the way back, it's easy to hoop in a taxi? or we have to wait like 30mins to get one taxi?
