Can you get married at Celestial Park? Our first date started there, and we want something small and meaningful for our ceremony.

I've seen several wedding photography sessions there. Never an actual wedding. Good luck.

You'll want to reach out to the town of Addison and ask. Some towns are OK with it, others may require a permit you'd have to pay for and/or have limits on people and space. Here's their contact info: https://addisontexas.net/index.php?section=contact

I'm not sure, but I would think you would be able to contact the Parks and Recreation Dept and find out. I don't see why you wouldn't be able to, personally
