Came on a Sunday afternoon with a couple other adults. I was really impressed with both the layout and the tanks. The attractions themselves surpassed my expectations. I'm not sure how they manage to keep the glass so clean with so many kids pawing at it with their grubby hands, but I was impressed. The jellyfish area was very cool.
I think I would've enjoyed it a lot more if I had gone in the evening or to an adults only event (no fault of Ripley's obviously). I don't think I've ever seen so many poorly behaved kids in my life. Kids whining, crying, screaming, pushing past people, etc. It got a bit better on the conveyor belt walkway, but in other areas expect bottlenecks. If you're reading this and planning on bringing your kids, maybe teach them some manners instead of letting them run around screaming like it's a playground (hint: it's not).
4 star rating based on the attraction itself considering the price (it's a little steep, but that's to be expected). While it didn't affect my score, beware of the screaming banshee children and their complacent mombies.
