The Aquarium is VERY nice. It's worth the trip, and if you live close, get the pass and go again. Twice within a year and the pass is paid for. Any more than that and you are going for free.
Also, my fiance and I went two years ago on New Years Eve for 100.00 and it was AMAZING. They had crab legs and fresh food served in several different areas, a whole room of desert, a live band and a DJ/bar area.
