One night accommodation resorts in ontario

Hello! We are gettsing married next summer, July 7th! We have been hitting a bit of a snag with venues and required number of stays. Basically we are looking at a private ceremony with under 20 people and then having the reception with 50-60 approx people. So for our guests who will be attending the ceremony we are requiring a two night stay but for our guests only attending the reception they will only require one night stay. Any place we have contacted will only do a 2 night minimum stay, which means our reception guests will have no accommodation at the resort. Sigh..any one have any venues they could suggest???! We are looking for an outdoor/beach type wedding in a lodge/resort type setting. More country than city. Somewhere that offers ceremony, reception and accommodation. We are in Bancroft, Ontario and would love something within 1-2 hours from us. We've been searching Peterborough, Ottawa type locations. Any help/tips is much appreciated! We've contacted over 10 venues and no luck yet. Do these type of resorts not exist?!
