Time’s ticking, choose venue or keep looking?

My heart is set on a wedding in September or October. I found a couple places in budget, both I like in different ways. They seem to book very fast! They both have a date left in September and/or October. I tour with both venues this Sunday and I’m tempted to just immediately put down a deposit if we love it in person on the spot. One is well known, Noah’s Event Venue and another venue locally that looks similar.

However, there’s another venue we are touring next Tuesday. I’ve always wanted to get married there but the more I learn about it the more I question it. It’s industrial yet romantic, near downtown, beautiful skyline of the city, and you can bring your own alcohol. Sounds good except the only room they have left available (two dates open September) is very unique. It’s split level, the top is where we eat, it overlooks downstairs where it’s the dance floor (like a hole in the middle of the floor lol). I have to see it in person to get a feel.

From reviews, people said it wasn’t an issue being split level. It holds like 180-200 but it looks tight.

Anyway, do I visit the venues Sunday and decide immediately so I don’t risk losing the dates? Or do I wait until Tuesday to see if the place I’ve thought I always wanted will be the one?
