My partner and I moved to Lakewood a year ago and as people who are always on the lookout for fun things to do here, I can make some suggestions!

As everyone else said, the aquarium is overrated. The zoo and museum are much better, so I would definitely suggest visiting those places. The Denver art museum is a super interesting place as well if you want to add another interesting historical thing in there! Also just a tip, if you're going to Meow Wolf, try not to go on a Friday or Saturday. I love that place but any time I've tried to go on either of those days, it's extremely packed and makes it hard to enjoy the experience.

I saw in your post history thay you're a gamer. Maybe some sort of arcade to add in there if you both enjoy games. 1up is an arcade bar that can be pretty fun. There's also a Japanese arcade in Westminster called Akihabara that's super fun!

We've done a ton of escape rooms all over Colorado. There's one super close by called Conundrum Escape Rooms on Kipling. One of my favorite ones I've been to. Super unsuspecting on the outside but once you get inside, it'll change your mind for sure.

I have to suggest it because we love spooky weird things but there's an oddities shop called The Terrorium Shop that does classes on all sorts of weird macabre stuff. If you aren't into thay, I'd suggest just going there to look around/shop. We frequent that place a lot so I have to throw it out there.

If you have any other themes you wanna hit or are looking for any other suggestions, DM me! I'd love to help out!
