Hi Milly,
Moving to the Caribbean always has it's share of issues, but if you can take things in stride and with a sense of humor and adventure you will do just fine.
I would recommend living up in the north, ie Rodney Bay area. Then you will be close to the marina, where most of the early evening socializing in the Expat world takes place. The gyms can be a great place to meet friends, both male and female.
Send me a private message, and I can give you some contacts such as real estate agent, names of the gyms, local eateries, etc. for when you are here in March.
You will get hit on, there is no doubt about that ... but, an "are you kidding me look" and a strong "no thanks" will generally send them on their way.Â
Cheers,
Danielle
