Vegas Baby! Need Help or Suggestions

October I have 2 vacations booked. One week in Vegas with some friends (celebrating a divorce for one of them, it was that bad) come back on Thursday and fly out on Saturday to Ireland for 4 days with my sister and friend ( Halloween Festival).
Well we all decided that even though we got cheap fares for the Irish trip, to rent a car, hotel room, food, and gas would be too expensive for that little amount of time so we cancelled it today. Now I am thinking hey spend 2 weeks in Vegas, one week with my group then have my sis and friend come out for the second week. But I have never been to Vegas so I don’t know if 2 weeks is a long time.

Any suggestions? I don’t want to waste money if it is not worth it but I don’t want to stay home either.:beer:
