Receptionless Wedding Okay?

I'm planning a small garden ceremony later this summer with around 10 guests. We'll meet around 10am, and I see the ceremony and family pictures being done in about 1 hour. Would it be rude to just end it there and send everyone on their way?

It would be difficult to setup anything foodwise at the venue, and the alternative is that we could meet up at a restaurant nearby. I would prefer to just end the event after the ceremony, but I also don't want to be rude to my guests.
