Babymoon Suggestions - March from NYC

Hi! As title indicates, planning a babymoon in March, traveling from NYC.

We were originally planning April, but per doc's advisement need to move it up a couple of weeks. Ideally, we wanted to miss some of the March peak travel but will have to suck it up.

Looking at Anguilla as we want 5 nights somewhere to relax, eat and enjoy some light activities. Aurora was appealing given the golf course for my husband. FS unfortunately prices jump up to $2,600/night to start which is out of range for us (willing to do $1,500 a night).

Any other suggestions of islands and hotels? We have done Mexico and Jamaica plenty, so looking for something else. Would like beautiful beaches, good food and somewhere to mostly veg out and enjoy the spa.

Thanks in advance!
