You'll have to Register with the Park Service prior to you Family Reunion because of the camping sites that are available. Also there is Camping spots for travel trailers and Motor Home's as far as cabins there are cabin's for lease or for Rent during the event with the Reunion. You will have to call Wallowa Lake State Park and work out the details.
They fill up a year in advance pretty much your you'll be lucky to get a camp or cabin Camp spots tents that stuff you might get a spot you can put your name on a list and try to do it that way you might get called for a spot that's about the only thing you can do I cancellation Maybe
Not sure how many cabins they have in the area. I do know that you have to book them way in advance. They fill up fast. I know they have camp grounds there also. They probably fill up fast also.
