Sandy,
Did you try looking into Villa Del Palmar Flamingo?? My guests are staying there..ive been to Nuevo many times as my parents own a condo there, and it is by far the nicest resort ( other than grand velas) there are kitchen in all of the rooms, and many different options ( 2 bd room/3bdrm/studio etc). The grouds are amazing, and the pricing is great. There is an all inclusive option for $65/day usd, and a grocerie store on site with everything you could need. I was far more imperssed with this resort than villamagna, and really liked the different options for my guests.
