We didn't go when DD was that young, but he might have a problem with the Volvo Jr Driving School - DD does the full-size version, and every single time she's been on it they have every single kid tell them their age (mom/big sibling can't say it - every kid says their own).
If he's 32" he's limited on what he can ride, but for that age there's tons of fun without riding. Dino Dig now gives out pails and shovels for free, there's a lot of things to spot throughout the park, various placces to build with blocks, playgrouds to play in, and more water fun than you'll want.
In the park there's a sheet - "what to do when you're two" - it's red and usually right there when you get in. I think I've seen it on the website, too, but I'm not spotting it today.
Have fun!
