That being said...
(This area you do have play room but it's a matter of choosing the people you know as well. This is not an event for strangers.)
I don't really want that, I'd prefer something a little more intimate.
I plan on giving the hostess a pre-made list of people I'd like there. :)
The space I know won't be very big and I'm wanting the cost to stay in a reasonable range. I don't see the need for lots of money to be spent. This may be an unpopular thing to think when it comes to not wanting children there but I've seen plenty of mom's on message boards who agree and have voiced the same. Remember, the idea is to keep stress off your hostess, her comfort level should be a concern to you. If she's stressed, you'll probably be stressed. You don't need that!
Just know you do have the final say.
Whatever you decide, just make sure the lines of communication are wide open and you're careful at how things are worded so nobody gets insulted. That's the last thing you want to do!
And talk about who you want on the guest list... Do you want a small event or a bigger one?
Not internalizing and talking with the hostess will help take that burden off your shoulders!
Be blessed and remember to relax,
