Definitely recommend making a reservation unless you are planning to go on a Monday evening when it's slow during dinner. When you make the reservation ask for the best seating available for your special night!
Cal to make sure, but we'll worth the cost. The view is spectacular at night.
As far as a package, I wouldn't know. But if you make a reservation for the restaurant you won't have to pay to go up. The restaurant on top, dinner at dawn, I recommend it.
