Need some venues for our Men’s Bukkake events in Royal Oak, Michigan

I have been holding monthly Men's Group Fun events, I have done hotels, but sometimes we have gotten over 57 guys at one time, which causes some problems for hotels. I was thinking there has to be some hotels that are more "Swinger Friendly" but can't find any information. So if anyone knows of any hotels, or even better venues, that would be great. We have 80% straight married guys so going to a bath house is not usually a good option. If any one wants to host at a private, residence let me know. Any help on hotels or venues would be great. Thank you
