Outdoor Fall Dinner?

Depending on your usual local weather for late October it's probably going to be too cold (I'm thinking of all of us Midwestern kids in Halloween costumes over our snowsuits 😂). I also agree that without tables in your reception space people might feel like they don't have a home base. As it gets colder throughout the night people won't want to go back outside to sit down. It sounds like a beautiful idea, I just don't think that the time of year is great for that type of thing.

I'd talk to your coordinator and have a plan for either or that can be determined the week of.

I'm also in the midwest and we're getting married and having the reception completely outdoors. It's so hit or miss, and lately it's been warmer in the fall months that typical, so it's a big gamble.

Come up with a plan for how dinner outside would work, and then maybe set-up a good handful of table inside for the dancing portion. They're not going to do a set-up for your event until the day of or night before anyways, so establishing "We'll do dinner outside as long as it's as the low is no less than 70 degrees, if it's expected to be less than that we'll do everything inside" should work. Week of you guys should have an estimate from the weather forecast on what it looks like and you can determine how to move forward from there.
