This December, I took my wife there for her birthday. Since I spent all my $$ on this addiction, it was a good thing we had 2 free passes. By the way, I think the Entertainment Book usually has a 2-for-1 coupon. EmilyB - if you need one call or pm me.
It was definitely worth a trip there, especially since its been years since my last visit. Actually, I used to give NightStalker tours - where you take groups of Scouts or Guides through at night, show 'em behind-the-scenes, have a snack & then sleep in the Beluga exhibit with a big smiley face staring at you as you snooze off, only to have the same (maybe dif) smiley faced Beluga staring at you in the morning. Miss those days.
Yeah, so I agree with those who say the new Van Aquarium is worth seeing. My wife loved the jellyfish exhibit (of course she wants one at home now

)
