Trip to Mexico

How i wish that the trip is for me. It is actually for my boss at work. She will be retiring soon , and she told us that she will spend her life now travelling with her kids. Wow! Isnt it fantastic? So her first stop would be Mexico. She said that she went there before and fell in love with the seaside suites that they got, so she would like to spend quality time with her kids there. She got the all inclusive mexico package , and it already covers their accommodation and food for the entire stay. I am asking her for an estimated budget needed, and she told me that she'll give me a copy of her budget sheet once she is done with the airfare. I plan to visit mexico too with my family, maybe by next year.
