two families - looking for advice

My family of four (two adults, 2 kids 15 & 10) and another family of four (two adults, 2 kids 15 & 12) are in the begining phases of planning a surpise trip for the four children for this summer......probably mid-June.....

To start with, based upon what's available on Abaco, where would you recommend we stay? A large house or villa, two smaller houses next door to each other, condo units next door? A large villa would need at least four bedrooms......

Any suggestions?
