Dean Unglert is opening up about his upcoming wedding to Bachelor in Paradise costar and fiancée Caelynn Miller-Keyes.

While the BiP alum can't wait to finally be married to his bride, he admits that his preference would be to keep the celebrations more chill than Bachelor-level thrill.

"I really just want to go to a courthouse by ourselves, then just sign the papers," Unglert, 31, tells PEOPLE. "But we're having a big party. It'll be fun, I know it'll be fun. I just hate being the center of attention."

Still, Unglert is excited for the couple to become husband and wife. "I'm looking forward to being happily married," he says. "The rest of it will be stressful and painfully expensive — but it's all to lead us to being Mr. and Mrs. Unglert."

When it comes to making decisions for their big day, Unglert admits that his fiancée has taken the lead on most of the planning. "I just nod my head and say yes," he jokes.

And while Miller-Keyes, 27, is running point on all things wedding, they're excited to share their big day with the people they love the most.

"The venue, it's very unique, so I think it's going to be a really fun weekend  just with a hundred of our friends and family," Miller-Keyes tells PEOPLE.

She adds that she's already nailed down the location and found her dresses, and that most of the big items are already crossed off.

"I feel pretty good. There are moments where I get stressed. But we have entertainment, we have the flowers, we've got pretty much everything minus the little details of linens and place cards and stuff like that."
