70 % male 30 % female but when there's a batchler party or a Rainbow party ( there not that bad , they don't bug the women,lol) the ratio can go up to 90% We have Single women in our groups and we sort of take care of each other. Even though the ratios are skewed you will have a good time or better, cause the women have more choice. it can also change week to week with groups,, had a Nurses group in TTR Cabo one year that changed the ratio.
