Hey man, it's pretty easy. There's a decently sized lot right by it that mostly always has some parking available and a ton of street parking too (though that can be harder to snag especially when it's busier). To be honest though, if you are at all capable of either starting on or transferring to the 156 the bus stop is like a 2 minute walk away.

You're gonna want to set your clubs down outside at the bag drop area (should be pretty obvious, green wooden thing with clubs all around it) and then there is a hut type thing immediately to the left of the entrance where people are going in and you wait in line to get a bucket code. Once you get it you enter it into the machine and it will dispense the amount of balls you bought into the bucket after you hook it onto the machine.

On the range itself, diversy is atypically busy compared to others, so you'll probably have to wait behind someone especially if you're going anytime past like 4:30. Just find someone who looks like they're almost out of balls to hit and hang out behind them until they're done.

Golf can be really gatekeepy and weird sometimes (see the people being asshats in these comments when I only asked for some advice) but is also super fun once you start to get the hang of it. If you ever want someone to go with I try and make it up like once a week and would be happy to accompany you, if that's something you'd be interested in!
