I have created a checklist for you to use when hosting a party in an outdoor space. You can find it under the stats tab above. If you can, try and visit your space more than once, at different times of the days and check off the things on the checklist. When you are done you should be prepared for anything that may transpire at your outdoor party.
Here also is the link for my video demonstrating how to keep your tableclothes from flying away on those windy days.
I have an entire series of party tip videos which you can see here
