Choosing a venue

How do you know when you’ve found the right venue? We live in a HCOL area, and we have a limited budget. We’ve seen pretty much every venue we can afford, and there’s one we both like but it’s at like the tippy top of our budget, and comes with some additional expenses that another venue doesn’t come with (but we don’t love that venue as much). Both venues are beautiful, one is all inclusive other than alcohol, the one we like best is not all inclusive so we’d have to get a caterer and bartender and all kinds of extras. We’re going to set up second tours for both of them and get some other opinions. But how do you know when to say yes, and when to keep looking?
