What can two 21 year olds do in Aruba?

Question

My boyfriend and I are going to Aruba in a week, we are both 21 years old and looking forward to doing lots of fun stuff. Has anyone been there that is my age?? What kind of stuff is there to do at night (bars/dance clubs). Also, are there any suggestions of things to do during the day?? My boyfriend wants to go snorkling... anyone know any good companies that take you snorkling??? Let me know! We need all the help we can get considering we just planned this yesturday!!!!! Thank you!
