Good price on Chair rentals for 1 hour!

I would almost have blankets for people to sit on, or tell them to BYOC. Depends if the look of uniform chairs is really important to you or not.

I'm not sure you would find anywhere that would rent them out for just an hour, and then someone has to wait with them for pick up. If your ceremony has only 40 people I think you can pull off having them stand.. how long will your ceremony be? Mine will be about 15 mins in totally probably, so if you're opting for a short ceremony people will be fine.. or you can bring blankets and have people sit on them.

I don’t think any chair company would rent the chairs out for 1 hour.

every chair company I’ve inquired with prices per chair. The cheapest I’ve seen so far is $5/chair.

Could you have people bring their own chairs? Or ask friends and family to borrow some lawn chairs?

I figure you've already contacted all of the vendors for event rentals Quebec on Wedding Wire already, but if none of them are what you are looking for then perhaps you could try contacting some local halls and community centres that may be willing to rent theirs to you if they aren't in use at that time and day?

Otherwise, seeing as how you are already having a park wedding it wouldn't be too outrageous for you to tell your guests it's BYOC (I would have no problem with that - but it depends on the type of look you want).

Im not sure what kind of feel you want but you could always do a bring your own blanket or lawn chair
