I opted for the bulk package: biodome, insectarium, olympic tower, stadium and the botanical gardens, all on a student budget (they didn’t check my non-existant ID) and it was worth it. The Biodome had the 4 different ecosystems, none were too exciting but the aquariums were great. I’d never seen large sturgeons swimming naturally, usually they’re fighting on the other end of my fishing line. I went in the middle of the day and there were elementary school field trips happening at the same time. It was like swimming in a guided sea of kids squealing Quebecois, it was like a nightmare. Try going later in the day. The tropic climate was so hot and muggy but they have drinking fountains around every turn.
