I took my 3 year old son to SeaQuest on a Saturday during peak times so YES, it was very crowded and parking was a mess! But what do you expect?? This is Vegas and there aren't very many things to do for kids so of course everyone will flock to this place! The cost for both of us plus 5 tokens to feed the animals was right around $40.
That being said, I was very pleasantly surprised! I didn't expect for the Aquarium to be so large and house so many animals because it was inside of a mall but I was so wrong! My son had a blast running around for about 2 hours, feeding and touching the fish whenever he could. He loved the baby turtles (so cute!) and the sting rays the most out of all the other animals that were on display.
This will be short and sweet: in conclusion, my son and I loved this place! I wanted to pay them a visit before I purchased an annual membership and I was sold! Even though it's quite a drive away from us, we will be back again and again...it was well worth it!
