We have a small group of ( 10 ) people doing the Eastern Caribbean out of Miami in Dec. If we use the airfare from NCL it will be approx $4200 per couple flying from Las Vegas to Miami, and $3500 per couple without. Round trip flights are $390 per person out of Vegas, non stop which will make it approx $4300. Really thinking for peace of mind, being able to choose seats this will be the direction we go.
