Unconventional Wedding Planning

Hi guys! We are getting “married” in June. We already had the official ceremony for personal reasons, but our family wasn’t able to be there so we are sticking with our original date. We are in Miami and trying to plan a get together with our family and friends to celebrate our marriage. Does anyone have any budget friendly ideas regarding where or how we can spend time with everyone and possibly renew our vows? We are open to any ideas, parks, camping, anywhere we can get everyone together to celebrate and enjoy each other’s company but having trouble coordinating it all in such a short time frame and small budget. Any suggestions would be very appreciated!
