Southern California Help With Legoland Admission Tickets!

[Flattes]

Hello,
I am hoping one of the experts on here can offer some advice as I am very confused! We are heading down to San Diego and will be stopping in Carlsbad for a night so we can take the kids to visit Legoland. We arrive there on a Friday afternoon and plan on spending the whole day on Saturday at Legoland. I have pre-purchased tickets for Legoland only for one day. However, we are thinking of visiting SeaLife Aquarium on the Friday afternoon - can I just do the $20 upgrade to visit or do I also need another day of Legoland admission? Having never been, I have no idea if these are two separate entrances or if it is all just part of the same resort - sorry for the silly question, just want to be prepared!
Thanks

It was separate entrance a few years ago, both at the front of park. If you're going to SeaWorld I would skip the aquarium at LegoLand. Not sure if it's worth the $20. Another cheaper alternative would be Scripp's Aquarium at LaJolla. This is one of my favorite aquariums, you can spend a couple hours or whole day.

No help on pricing, but I don't think it's worth 20 either. It's the tiniest little thing. It's okay if it's already included in your price and you've done everything else. Not worth extra $ though.
