What can a 20 yr old do at an all inclusive resort in mexico/aruba?

You are a VERY IMMATURE 20 YEAR OLD if you have to ask what you can do at an all inclusive resort in Mexico or the Caribbean... you sound like "Baby" in SATURDAY NIGHT FEVER.. geezus.. by the time I was 20 years old I had been in about 20 COUNTRIES and had been living in Europe, supporting myself by busking with my guitar and playing piano for the past 2 years.
