We are getting married in July at a lake lodge. Following the ceremony we will be having a lunch reception. All of that should be finished by 2:00 and weather pending, we will spend the rest of the day swimming at the lake. That evening we will have a very casual BBQ down by the lake for the guests that have stayed. We want to put an insert in the invitations that invites our guests to bring their swimsuits, lawn chairs, and coolers and spend the day hanging out but are struggling with wording. Any help would really be appreciated.
