I have friends who own a studio at Atrium and I stayed in a different studio at Atrium and both were nicely spacious I thought, with full kitchens. The studios at Simpson Bay Villas have a DINKY balcony and a mini (think college cube!) fridge and I think a microwave. I would not hesitate to stay at Atrium again. If the choice is a studio at Atrium versus a studio at Simpson Bay Villas, I would definitely pick Atrium for space. The only thing is the Atrium would probably not be ocean view. If you could get an ocean view room at Atrium, it would be a no-brainer to me.
