We are renting inflatables and doing a paint slide (the strong landscaping fabric with paint on it...you wear white and slide on it). But I live on a farm with plenty of space for this stuff. It is a little redneck-ish but that is what my bridesmaids suggested and I am all for it!
I drink but my MOH (my daughter) is 14, one bridesmaid (her cousin) is 19, and my bff, the other bridesmaid, is 32. Needless to say, we aren't going to be doing anything involving drinking. We decided to have a pamper day with mani/pedis and massages instead.
I went to a bachelorette party when everyone was underage (bride was 19..) young I know! But, we all went to a lake and rented a cabin and had smores and played paint twister and went cliff jumping! It was a blast with no alcohol, so maybe something like that?
Bowling, dinner and a movie. There are lots of things!
FH and I have discussed letting our BP know we'd prefer a joint one if they should throw us one. We have an escape room not too far which would be fun. Bowling. Painting and spa day like others have suggested.
One of my friends did a bachelorette weekend. We went away for the weekend and rented a cabin and went shopping and canoeing all weekend. It was really a good time!
