Oasis hotel and resort in cancun?

my boyfriend and i are about to book a vacation at the oasis hotel in cancun. just want to know if i should go through with it. were both 20. were looking for great drinks especially being that they're unlimited, great food. we don't want all of the restaurants to be buffet styled either. beautiful rooms. lots of activities, amazing night life, young crowd (18 to 26) , a diverse crowd, just endless fun... also if anyone knows of how much the excursions and water activities are like parceling and jet skeeing are please let me know. any advice is appreciated. thx
